Plug in a PS/2 mouse, and it works.

See product errata for the AMD-768 (#10):
"Multiprocessor system may hang while in FULL APIC mode and IOAPIC interrupt
is masked"

I'm currently running similar setup (same MB, Redhat 9 + 2.4.22-pre7) without 
any problems. If the PS/2 mouse is removed i get exactly the same problems as 
you described. 

And it's not only the IDE that is affected. E.g. doing 'ifdown eth0' causes 
the system to hang (at least for me it did), so turning off the DMA is not 
a solution.

no. (it will not solve this problem)

> Does this problem affect any inter-CPU processes like OpenMP?

no, when you have the PS/2 mouse.

Same problem appears with all motherboards using AMD 768 (rev B1 or B2). 
(Correct me if i'm wrong. Maybe some manufacturer had made workaround for 
this problem...)

AMD760MP - Troubles with MSI K7D

[Heimo Truhetz]

Hello out there,

I have two Athlon MP's 2600+ mounted on a MSI K7D-Master-L with the famous 
AMD-768 (Opus) chipset (latest BIOS 1.82).
Actually I'm using debian's 'woody' distribution with the kernel 2.4.22-pre8, 
glibc 2.2.5 and gcc 2.95.4.
I have problems with the IDE support:
On the hardisk (Maxtor 6Y120L0 - 120GB) there is a 1.4 GB file, I want to 
copy. But when I try this, the system stops with the error message:

attempt to access beyond end of device
03:09: rw=0, want=976094472, limit=109948828

and I have to push the reset button.

When I switch DMA off by using 'hdparm -d0' everthing works fine, but the 
hole copy-process takes about 8 minutes!

Taking a look at 'lspci' shows the following:
# lspci
00:00.0 Host bridge: Advanced Micro Devices [AMD]: Unknown device 700c (rev 
11)
00:01.0 PCI bridge: Advanced Micro Devices [AMD]: Unknown device 700d

(rev 07)

So, the AMD is 'unknown', although 'dmesg' tells:

Are there any solutions or workarounds to fix these problems?
Do I have to upgrade the glibc or any other system components?
Does this problem affect any inter-CPU processes like OpenMP?
Do I have to change the motherboard? Which mobo's are said to be reliable?

Kindest regards,
