Description Mike Tisdell 2000-07-19 18:50:01 UTC 
When booting a 5.0-current kernel on a Toshiba 2775 Laptop the system hangs after loading the pcib0 driver. A hard reset is required to reboot the system. Both the gziped kernel on the on the installation disk and a kernel I built from the source tree have this problem. I did build a 5.0 kernel with the /usr/src/sys/i386/isa/pcibus.c from the 4.0-RELEASE source tree, and was able to boot the system with this kernel. 
 
Side note: are there any pcmcia ethernet cards currently on the market (i.e. that could be ordered and purchased) that will work with FreeBSD? Preferably 100baseT.

Fix: 

compile the kernel with the 4.0-RELEASE version of /usr/src/sys/i386/isa/pcibus.c
How-To-Repeat: Boot a toshiba 2775 (and I expect other 27xx models) with a FreeBSD 5.0 kernel.

This problem crept in between rev 1.57 and rev 1.62 of 
src/sys/i386/isa/pcibus.c .  Mike, could you take a look?

Does this problem still occur with either 5.1 release or 5.2-RC2?

I'll take this one.

1) Does this problem still happen on either 5.x or HEAD?
2) Does it go away on 5.x and/or HEAD if you 'set hw.pci.enable_io_modes=0' in 
the loader?

I have seen this problem on my Toshiba laptop as well. I was able to get 
around the hang by setting hw.pci.enable_io_modes to zero at boot time.

This problem should be fixed in HEAD and RELENG_5 now.  Can anyone please 
confirm that?
