Subject[2.6.25-rc5-mm1][regression] ia64: hackbench doesn't finish >12 hour
Hi

I tested following.

% ./hackbench 130 process 500

(this parameter mean consume all physical memory and 1G swap space)


2.6.25-rc3-mm1: works well
2.6.25-rc5: works well
2.6.25-rc5-mm1: doesn't finish >12 hour

my bisect indicate the cause of bug is git-ia64.patch.
and, git-ia64.patch of 2.6.25-rc5-mm1 contain following patches.

[IA64] cleanup and improve fsys_gettimeofday
[IA64] Multiple outstanding ptc.g instruction support
[IA64] VIRT_CPU_ACCOUNTING (accurate cpu time accounting)


unfortunately, I don't know how investigate more ;-)
Please any suggestion.
