So 2.6.24-rc3 was OK and 2.6.24-rc3-git2 is not?
Yes, the 2.6.24-rc3 was Ok and this is seen from 2.6.24-rc3-git2/3/4.
just to make sure: this is a real lockup and failed bootup (or device
init), not just a message, right?

Hi Ingo,
This softlockup is seen in the 2.6.24-rc4 either and looks like a
message because this is seen while running tbench and machine
continues running other test's after the softlockup messages and some
times seen with the bootup, but the

i think it would be OK to do half of this: make it easier to preempt

It's not a problem to super-preempt positively reniced tasks, but it
can be quite annoying if negatively

thanks! Sorry about that: we cross-built on ARM but not on SMP non-x86
platforms so this dependency/breakage went unnoticed.

could you try the full patchset that Travis has just sent and which

Some place in there. The CONFIG_SMP=n path in ia64 makes quite
radical changes ... rather than putting all the per-cpu stuff into
the top 64K of address space and providing a per-cpu TLB mapping for
that range to a different physical address

ah, that was the vital clue. The patch below makes the small memory

I applied this on top of the git pull from
/kernel/mca_asm.S and the
position of the percpu data.
Is my analysis correct? Do you like my fix and does the patch build and
boot on your system? Thanks,

I'll start digging on why this doesn't boot ... but you might as well
send the fixes so far upstream to Linus so that the SMP fix is
available (which is all anyone really cares about ... there are very,
very few UP ia64 systems in existence).
