Trying to boot FreeBSD 7.0R on an ultra5 resulted in the kernel failing to proceed while displaying the following message: interrupt storm detected on "vec2016:"; throttling interrupt source Fetched 7.0-RELEASE-sparc64-disc1.iso, put it on cd, checked md5 and sha256 checksums, burned it successfully, and inserted it into my ultra5. What follows is an edited script(1) transcript of the session over serial, using tip(1) from another FreeBSD(/i386) system. Edited are: removal of ^M and .^H sequences, and removal of duplicate lines with edit note and count, masked mac addresses. Shown is output of boot -v.

Could you please check whether > the cabling and the drive are ok and functional? Apologies for the narrative. The answer to your question is in the next and the paragraphs before the last interrupt storm. The rest is me attempting to be thorough. In short: Yes, overall I think they're ok. I just checked and the cable on the hard drive end said 'click' when I pushed on it on the drive's side. A marginal connection seems likely. The other connections seem to be ok, if old ata33-only cables. The cdrom I swapped with a then-new dvd drive (IE it's not sun-original) and it should be ok. It was used for installing 5.4 and solaris 10 from dvd a while back. The system has been mostly offline in the meantime. I'd like to note that booting 5.4 (which I did before and after trying to boot 7.0 for the first time) didn't have the problem, but 7.0 did, both while booting from cdrom and from hard drive, so whether that was an actual marginal connection, I guess we'll find out next (see below). I probably should've made the connection between the one and the other notice, altough not knowing what vector 2016 was, I substituted ignorance and went ahead. I noticed that *eventually* it'll go through, maybe prodded along by sending a couple of breaks, at which point I rolled a 7.0 base+man over the previous one. Once it booted it stopped complaining, mostly. Then I checked out src and built a custom kernel. Installing it would get me DMA errors when it got to the twe module, altough (again) brute force eventually got around it. On a lark I checked out the relevant bits of ports and installed smartmontools, and ran an offline test. The output looked all green except for a non-zero but low (14) Reallocated_Event_Count. So I think the hard disk drive and presumably the dvd drive are in reasonable shape. While I'm writing this the machine sat twirling away just as it did before, *very slowly* twirling away loading the kernel (which it did do much faster even with the interrupt storm messages coming up later) and eventually getting to a bootstage, but it will then panic. If this keeps up after I get a fresh image on it, I'll ask for help about that. Consoles: Open Firmware console Booting with sun4u support.

Compile #0 worked, though. I'll see what happens when I get it to boot GENERIC again, compile again, and so forth. Now, long story short: I double-checked the connections, closed up the case, and booted GENERIC from the install cd again.

Author: mav Date: Wed Dec 9 17:23:08 2009 New Revision: 200298 URL: http://svn.freebsd.org/changeset/base/200298 Log: MFC r200121: Do not ignore device interrupt if bus mastering is still active. It is normal in case of media read error and some ATAPI cases, when transfer size is unknown beforehand. PCI ATA BM specification tells that in case of such underrun driver should just manually stop DMA engine. DMA engine should same time guarantie that all bus mastering transfers completed at the moment when driver reads interrupt flag asserted. This change fixes interrupt storms and command timeouts in many cases.
