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.
