2.4.5-ac6: IDE deadlocks/bugs + unexpected IO-APIC

[Xavier Bestel <xavier.bestel@free.fr>]

Hi !

I have an ABit VP6 (Dual PIII, infamous VIA686, onboard IDE + onboard
HPT370). This is a new machine, so I didn't test it on several kernels.

Using 2.4.4-ac11 (SMP), it started to deadlock really often when
accessing the new disk (Seagate Barracuda, udma5, big reiserfs partition
+ swap) I put on the HPT370, even when mounting it.

Using 2.4.5-ac6, things are much better, but sometimes it hangs at boot
around "RAMDISK: Loading 4096 blocks [1 disk] into ram disk ..." - I say
"around" because sometimes it displays "ACPI: Core Subsystem version
...", and sometimes not.
And sometimes it still hangs randomly. No messages, nothing special in
the logs except an "unexpected IO-APIC" (that's why I put linux-smp in
Cc:) and 40 Megs (!!) of:

dated between Jun  2 23:11:58 and Jun  2 23:14:10

The thing that annoys me is that today, I just found the my /etc/motd
with junk appended (a bit of C code). /etc/motd is on my root partition
on a disk (Seagate ST36531A, big ext2 partition + swap) NOT on the
HPT370, but on the first onboard IDE.


I know (now that I looked a bit in the archives) that the VIA686 chipset
isn't reliable. Any hint to make my PC work while keeping reasonable
performance ?
What should I do to help ?
