Any success?
I think I've been hit by a similar problem trying to upgrade from
FreeBSD 5.x/i386 to 6.x/amd64 on an AND Athlon 64 X2 3800+, with a
Tekram DC-390 SCSI adapter.
When booting from the FreeBSD install CD-ROM (6.1-BETA3 as well as
6.1-20060320-STABLE-amd64), the boot stops with a panic; I'm not
sure it always does at the same place, I noted one at device scan:
______________________________________________________

Uptime: 6s
Cannot dump. No dump device defined.
Automatic reboot in 15 seconds - press any key (etc.)

Another happened after card detection; from memory, I think it was:
______________________________________________________
sym0: <1010-33> port (etc.)
panic: sym: VTOBUS FAILED!
Uptime: 1s
(etc.)

My dmesg with FreeBSD 5 follows. I haven't yet tried 6.x/i386.
Thanks in advance,
Cedric Ware.

I am seeing this too. Tyan S2865 motherboard, Athlon X2, 6.1-RELEASE-p5. Booting from a 6.0-RELEASE/i386 CD seems to work fine, at least as far as the fixit shell. The behaviour below is consistent; it always dies with "panic: sym: VTOBUS FAILED!" after finding the sym0 controller. dmesg below.

The problem seems to be caused by the sym driver assuming that the virtual
address of the memory allocated by bus_dmamem_alloc will be aligned to an
address 2*PAGE_SIZE. The physical address is aligned like that, but the
virtual address isn't. This also breaks the buddy algorithm.
Here are the changes I have made to make it work on my system. Summary:
Allocate additional pages and adjust the virtual address if necessary to get
memory with the right alignment.
Other changes (possibly incorrect):
- Adjusted the contigmalloc call because the boundary argument didn't make
sense to me compared to the man page.
- Adjusted the highaddr argument in the bus_dma_tag_create() call, again,
the usage didn't really match what I expected from the man page.
Little testing; I have used it to boot and dd over an old 4GB drive. With
the original version it never made it past sym_pci_attach.

Alternative, smaller, cleaner, patch.
Removes amd64 specific case by splitting the sym_hcb struct so that we don't
have to cross page boundaries.

Hello! The 6.2's install shamefully paniced on our amd64-system -- due to this bug. We had to borrow an Adaptec card and then switch back to the Symbios ones after applying Jan's patch-1.diff Unfortunately, that patch allowed us to collect a number of kernel dumps: http://aldan.algebra.com/~mi/bonkers-crash-0.txt - GPF http://aldan.algebra.com/~mi/bonkers-crash-1.txt - spin lock http://aldan.algebra.com/~mi/bonkers-crash-2.txt - GPF (there were more panics with "spin lock held too long", but no kernel dump took place, perhaps, because the dumpdev is attached to the sym-card too) The second patch, posted by Jan on Sep 26th seems much better so far, although the driver's use of Giant is still disappointing... Maybe, Jan's enhancement can be committed to stop the VTOBUS-panics from happening again? Thanks! -mi The patch in the PR allows our two Symbios 875 boards to work with FreeBSD-6.2-recent. However, the machine continues to suffer from the "spin lock held to long" panics every few days. Usually, there is a double-panic, which prevents crash dump from occuring. But this morning it succeeded. The full trace is available at http://aldan.algebra.com/~mi/bonkers-crash-4.txt The panic is from kern_mutex.c. The value of the delay-counting i is, no surprise, exactly 60000000. I'm not sure, if it is the sym-enabling patch, that causes the problem, or something else. Either way, it would be very useful for an expert to look at it -- and commit the (possibly modified) patch too. -mi State Changed From-To: open->closed Slightly modified version of the last suggested patch has been committed. Thanks! se 2007-07-20 23:02:01 UTC

Log:
Fix Symbios driver on amd64: Since amd64 has 64 bit pointers but the same
4KB pages as i386, data structures that just fit in one page on i386 (and
on 64 bit architectures with 8KB pages) can be distributed over two pages
on amd64. This is a porblem in the case of the Symbios driver, since the
SCRIPTS engine in the SCSI chip operates on physical addresses and needs
physically contiguous memory. Earlier patches used contigmalloc on amd64,
but this version replaces part of a structure by a pointer to that data.
In order to not introduce an extra indirection for other architectures,
the change has been made conditional on __amd64__.
Earlier attempts to repair this problem are removed (i.e. the macros that
made amd64 use contigmalloc). The fix was submitted by Jan Mikkelsen and
modified by me to only affect amd64.

Ever since I switched to amd64, I have been having problems with my symbios / lsi logic 21010 scsi card. I tried it initially on an nforce2 chipset, and was getting this error message: panic: sym0 : VTOBUS FAILED! About a year ago someone was helping address the problem, and I thought that a patch he had made (6.0-current at the time) had corrected the problem. I think maybe this was just a matter of luck though, because now the problem seems to have resurfaced, this time on an nforce4 chipset. dmesg output follows: Copyright (c) 1992-2005 The FreeBSD Project.

Of course at either of these points the boot sequence halts and it gives me 15 seconds to reboot. Fix: So far I don't have a fix to the problem, but would be willing to try any suggestions or patches. I should note here also that my nvidia ethernet controller (nve) isn't working at the moment either, so no networking available atm either. How-To-Repeat: I've tried several combinations of enabling/disabling various motherboard components, but haven't found the exact recipe to repeat the problem consistently. There is clearly some randomness to the problem because I can boot twice in a row with the same settings and it will work one time and not the other. Some factors that seem to have some influence on the problem are the enabling/disabling of the onboard USB in BIOS and perhaps whether or not I enable or disable ACPI on the boot menu (you can see there are some issues with acpi from dmesg, but I can't tell if this is because of the symbios card or not). When I first booted up with the installation cdrom, I had to disable the onboard USB controller to get it to the install menu - this seemed to work consistently. Then once I started booting up from the hard drive, disabling the onboard USB didn't help. I re-enabled onboard USB and tried it again with ACPI disabled from the boot menu and it failed again. I rebooted one more time with USB enabled and ACPI enabled and it worked - the very same scenario in which it failed immediately after installation.
