I decided to try out the new 2.6.0-test2 kernel today but
ran into a problem with booting it. I narrowed it down to
the machine check expection code. I get this panic from
the kernel on boot when I have it enabled
CPU0: Machine Check Exception: 0000000000000004
Bank0: f606200000000833 at 0000000000004040
Kernel Panic: CPU context corrupt.
I disabled this option in the kernel and recompiled and everything
went smooth. I figured maybe there could actually possibly be
something wrong with the CPU but I can boot with RedHat's
2.4.20-19 kernel fine which I *think* includes machine check exception
code. I have no beef with leaving the exception code out but I figured
someone on this list may want to know.

Looks like corruption with your L2 cache. Odds are its heat-related.

Missing bugfix from the 2.4 kernel that never made it into 2.5.
Chances are you (and many other Athlon users) are hitting problems
because of this chunk..
Already pushed to Linus/Andrew.

The change looks rather suspicious to me.
Bank 0 is the data cache unit (DC)
Do you have an errata that says that the DC bank is bad on all Athlons?
Normally BIOS or microcode are supposed to turn off bad MCEs by
masking them in another register. Maybe the person's CPU has a
real problem that is just masked now, e.g. it could be overclocked
and stress the cache too much.
The original MCE was:
Status: (4) Machine Check in progress.

It's been in 2.4 for months, it solved the same problem there as
many people are now seeing in 2.6. The "I don't get MCEs in 2.4
but I get them in 2.6" reports are numerous, and I don't buy the
"2.6 stresses hardware more" theory for a second.

Hmm, I thought this was actually documented, but I can't seem to find
it in any of the docs I have. There are however gaps between the
errata numbers in a few cases, so its possible it was removed in
a later version of the revision guide. Richard ?

I recall seeing Athlon owners complain when I 'fixed' this problem
using an inverse of this patch in 2.4.19-pre3. For pre4, Marcelo
backed it out, and people were happy again.
Whether its documented or not, there are boxes out there that don't
like having that bank enabled.

The CPU's aren't overclocked and have worked fine for
me under much heavier loads than booting a kernel for
at least a year. Using the 2.4 kernel that is. Once
I remove the exception code from the kernel it boots
fine and runs fine under any load I put it under.

Should say 1.2 GHz processor I imagine. AMD and their
wacky naming schemes. This is before they had they
wacky number scheme.

It could be corrected ECC errors in the cache. If that
happens I would consider it a hardware problem
(now hidden with the disabled bank).

I maintain that such a magic hack needs at least a big fat comment.
I still find the change very suspicious, there isn't any errata that
says that bank 0 is bad on Athlon.
Also disabling a whole bank just for some buggy CPUs is quite a sledgehammer,
it would be probably better to identify the bank 0 sub unit that causes it
and only turn that off.
-Andi
Out of curiosity I decided to try this on some other Athlon
systems I have. I tried it on a dual Athlon MP 2400(2GHz)
system with a Tyan 2462 motherboard. Also I tried it on a
single Athlon XP 1800 with a Asus A7V motherboard. They
both booted fine with the 2.6.0-test2 kernel and the machine
exception code in it. So I am thinking either it is something
with the older CPU's or the CPU is actually borked. Like I said
though I have been using those 1.2GHz processors for a long time
with no problems.

Out of curiosity, I never got MCE on my system at home (last kernel
before one below was 2.6.0-test2, and it did not complain for
different kernels at least since November 2001), yet after recent MCE
changes I got during fsck:
MCE: The hardware reports a non fatal, correctable incident occurred on CPU 0.
Bank 0: f65980000000baff
System booted these 2.4.x kernels which are supposed to contain
off by one fix, without complaints (first number = no. of boots):
8 Linux version 2.4.20-30 (root@ppc) (gcc version 3.3 (Debian))

Any idea what's going wrong?
