Subject: Athlon/MSI mobo combo broken?

Hi!

I have now had two MSI mainboards and two Athlons with 1330 MHz, and
none of them works as advertised. When I compile an Athlon kernel (I
previously had an Athlon 900 with an Epox board, which was flaky and did
not boot reliably and the USB subsystem was unreliable, too), the
resulting kernel will boot only partially, get spurious errors like a
divide error in the reiserfs code trying to mount a reiserfs volume, and
finally panic on me because it tried to kill the swapper.

When I compile the same kernel for Pentium Pro, it works. How can this
be?

This is not my only problem with this combination, though. My network
card (tulip) only works in two of the six PCI slots, my 1995 NCR SCSI
controller only works two slots, and there is only one slot combination
with my sound card that actually works. When I start Windoze on the
hardware, it hangs trying to load drivers for the NCR controller.

Since this is now my second MSI board, my second power supply, my second
Athlon and there appear to be no thermal problems (judging from the
BIOS health display), I am out of guesses here. I basically replaces
everything in my PC and it still won't work.

Theory right now: Because the Athlon kernel does streaming memory copies at
full bus performance. Not all VIA chipset boards seem to cope.

I'd be interested to know if 2.4.6-ac5 Athlon optimised works on your board.
The reason for this is that it contains the official VIA fixes for their IDE
corruption problem rather than our own.

I fixed my MSI/athlon stability problems by reducing PS load. My next
purchase will be a 450W PS to replace my 300W.

Athlons are real power suckers, 300W is probably 'barely enough' for
typical PC.

I'd rather say it may be related to how your MSI board supplies power to the
Athlon, rather than the Athlon itself. I've been using ABit KT7A +
[email protected] for half a year now, without a _single_ stability problem -
and this machine is my primary workstation, being switched off basically
only when I sleep.

I have Matrox G400/YMF724/NIC/CDR/DVD/three HDs (two in RAID) and... 250W
PS.

A friend has purchased basically the same config, he has one HD less but his
CPU is overclocked to 1150MHz. He uses both Linux and Windows and also does
not report any problems.

cheers,
Milek
Ps. One probably important thing is that I'm only using HPT370 IDE
controller under Linux.

I have a MSI K7T Turbo (MS-6330) mobo (VIA-KT133A chipset) and had a go
with the 2.4.6-ac5 kernel with Athlon optimisations on. The overall
impression is that the combination is slightly more stable than kernels
without the Southbridge fix. I.e. I now manage to boot in single user
mode, however running anything as advanced as gcc is out of the
question: oopses all over the place and also some complaints from the
VM-system.

I am in no way qualified enough to go hacking around in the kernel
myself, but am quite willing to test any patches that might help towards
solving the problem.

Cheers,
