The two problems I see are: -- perfmon missing interrupts *even with CONFIG_PREEMPT turned off!* -- weird kernel page faults apparently during ia64_leave_kernel() (from the stack backtrace), but with an IP address in region 0, after some variable amount of uptime, apparently independent of anything happening on the machine (at least, I haven't yet been able to isolate anything that causes it). -- Dr Peter Chubb peterc@gelato.unsw.edu.au You are lost in a maze of BitKeeper repositories, all almost the same.
