I'm announcing the release of the 2.6.38.4 kernel.
All users of the 2.6.38 kernel series must upgrade.
The updated 2.6.38.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.38.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.38.y.git;a=summary
thanks,
greg k-h

not a biggie, just to let you know, the incremental patch didn't hit the usual
directory. It is currently sitting in /pub/linux/kernel/v2.6/ on kernel.org.

Oops, sorry about that, my fault, it should now be in the correct place
(give the mirrors some time to sync up.)
thanks,

With 2.6.38.4 the clock slows down and the affected laptop sometimes, e.g. for
the output of "ps axuw" to appear, needs an input from the keyboard or the
touchpad. Please find attached the kernel config file and the output of dmesg.
Commenting out the the lines
if (c->x86 >= 0xf && !cpu_has_amd_erratum(amd_erratum_400))
set_cpu_cap(c, X86_FEATURE_ARAT);
in arch/x86/kernel/cpu/amd.c makes this laptop work as before with kernel
2.6.38.3. I think these lines came with commit
d7b7f0c401303dd7eafcff11752fe74d3b75c766.
Do I have to use a kernel parameter to remedy the clock misbehavior?

Hmm, interesting.
Can you send also /proc/cpuinfo please?
Looks like your CPU is a single core K8 revE or something but we'd need
the exact family info.
Thanks.

It's an old family fh processor (CPUID 00020F42) that cpu_has_amd_erratum(amd_erratum_400) apparently hasn't picked up. Since all fh processors are affected by this erratum I'll replace "c->x86 >= 0xf" with "c->x86 > 0xf" (and probably fix erratum formula anyway).

Hi, what's the status of this please?
I don't see the fix neither in the -next tree.

Boris O will be coming up with a patch soon. We wanted to clarify the
