Description Need Real Name 2001-12-20 21:06:08 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

Description of problem:
I have a VA Linux 2230 box, with 440GX chipset, AIC7896 SCSI chipset.  
Yes, that one.  There is only 1 processor in the machine, and the install 
went perfectly.  However, when I boot up the machine, it hangs with the 
old timeout error.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.  Turn on the machine
2.  Watch it boot.
	

Actual Results:  SCSI timeout errors galore.

Expected Results:  The system should boot up normally.

Additional info:

I attempted the normal 440GX/AIC7xxx workarounds to no avail.  I tried 
passing APIC=0 to the kernel, but it was already a 1 CPU system with the 
uni-cpu kernel.

I'm using GRUB, but that shouldn't make any difference since it gets past 
that point.

When booting up and trying to load the AIC driver, I get:

Comment 2 Jeremy Katz 2001-12-20 21:53:00 UTC

440GX based boards are not supported; reassigning to kernel

Comment 3 Arjan van de Ven 2001-12-21 07:07:36 UTC

On 440GX motherboards you NEED to install the SMP kernel.
You can either do this by "upgrading" again, and then pick the smp kernel
or go into rescue mode (from the cd) and install the smp kernel in the chroot there

Comment 4 Need Real Name 2001-12-25 05:54:26 UTC

The assertion regarding the SMP kernel is correct.  Once the SMP kernel was 
forced onto the system (even though it only has a single CPU installed), all 
behaved as expected.  This also explained why I had installed 7.2 on a 440GX 
system with AIC-7896 before and it worked--the previous system has 2 CPUs 
installed.

Perhaps this should become part of the Errata for 7.2 and future versions?

Thanks for the effort.
