I upgraded today from 2.6.23 to 2.6.23.8 and started seeing a lot of
these in the logs:

I'm getting them in the hundreds but I had never seen them before this
upgrade. CPU is a single CPU, single core AMD Turion running in 32-bit
mode. Apparently they only occur when the ondemand governor is used. I
switched to the powersave and the performance governors for a while and
didn't see any message, but as soon as I went back to ondemand, the
messages started showing up again.
I see the problem might have to do with timers. In case it's relevant,
the available clock sources are acpi_pm pit jiffies tsc, of which
acpi_pm is the current one in use. I'm including the kernel config as
well.

Great, thanks for tracking this down.
Ingo, this corrisponds to changeset
a115d5caca1a2905ba7a32b408a6042b20179aaa in mainline. Is that patch
incorrect? Should this patch in the -stable tree be reverted?

Hm, I've never observed a problem with this in mainline.
Ah. The significant difference between 2.6.23 and -git is that the
former used sched_clock as the softlockup timebase, versus cpu_clock in
git. If sched_clock() is tsc-based, and the tsc isn't stable when using
cpufreq, then the softlockup with get confused and fire spuriously.
Ingo's fix to reporting exposed the fact that softlockup is terminally
broken in that kernel.
I think the best course for now is to revert it, since softlockup is
hardly a critical feature. The proper fixes would either be to backport
cpu_clock() to 2.6.23, or make it go back to using ticks.

hm, there are no such problems in .24 and the cpu_clock() and other
fixes i did were not picked up. Find the missing fixes below. They
should work just fine in .23 as it has the cpu_clock() functionality
too.
[ NOTE: the most robust thing is to make the .23 version match the .24
version of kernel/softlockup.c, so i included two other harmless
changes in this diff as well. ]

softlockup: improve debug output
Improve the debuggability of kernel lockups by enhancing the debug
output of the softlockup detector: print the task that causes the lockup
and try to print a more intelligent backtrace.
The old format was:
BUG: soft lockup detected on CPU#1!

=======================
Note that in the old format we only knew that some system call locked
up, we didnt know _which_. With the new format we know that it's at a
specific place in sys_prctl(). [which was where i created an artificial
kernel lockup to test the new format.]
This is also useful if the lockup happens in user-space - the user-space
EIP (and other registers) will be printed too. (such a lockup would
either suggest that the task was running at SCHED_FIFO:99 and looping
for more than 10 seconds, or that the softlockup detector has a
false-positive.)
The task name is printed too first, just in case we dont manage to print
a useful backtrace.

Can you try applying the patch below to see if that solves the problem
for you?

[<c0104f8a>] syscall_call+0x7/0xb
=======================
Note that in the old format we only knew that some system call locked
up, we didnt know _which_. With the new format we know that it's at a
specific place in sys_prctl(). [which was where i created an artificial
kernel lockup to test the new format.]
This is also useful if the lockup happens in user-space - the user-space
EIP (and other registers) will be printed too. (such a lockup would
either suggest that the task was running at SCHED_FIFO:99 and looping
for more than 10 seconds, or that the softlockup detector has a
false-positive.)
The task name is printed too first, just in case we dont manage to print
a useful backtrace.

Those are just cosmetic / cleanup changes.
Don't you need commit a3b13c23f186ecb57204580cc1f2dbe9c284953a ??

I don't think this patch will help; it only has cosmetic changes in

yes, it does need the cpu_clock() changes as i mentioned.

softlockup: use cpu_clock() instead of sched_clock()
sched_clock() is not a reliable time-source, use cpu_clock() instead.
but we only have cpu_clock() from v2.6.23 onwards - so we should not
apply the original patch to v2.6.22. (we should not have applied your
patch that started the mess to begin with - but that's another matter.)

i just forgot to attach the cpu_clock() changes - they are in a3b13c23.

Well, I can easily back that one out, if that is easier than adding 2
more patches to try to fix up the mess here.
Let me know if you feel that would be best.

Ok, I've now added that patch too :)
Hopefully this is all straightened out now, I'll go cut a -rc for the
next stable so people can test...

i'd leave it alone - doing that we have in essence the softlockup
detector turned off. Reverting to the older version might trigger false
positives that need the new stuff.

Ok, I'll see if the current round of patches fix up everyone complaints
:)

so just to reiterate, to make sure we have the same plans: lets leave
v2.6.22 and earlier kernels alone - and lets strive for the latest
patches and code for v2.6.23 (and v2.6.24, evidently).

I've validated that those patches make 2.6.23 behave on my
Niagara box.

Great and thanks for testing it! Arjan noticed the shortness of the 1
sec sleep too, my suggestion would be to increase the sleep period to
~50 seconds and the detection threshold to 60 seconds - that should be
large enough - instead of complicating the tick code even more.
