Hello,
I am sorry for bugging you guys here, but I've got a question and I think it
best fits here. I have an Acer laptop, namely TravelMate 5320 with a Linux OS
(uname -a gives: Linux seagull 2.6.30-gentoo-r4 #4 Sat Aug 15 01:29:44 EEST
2009 i686 Intel(R) Celeron(R) CPU 550 @ 2.00GHz GenuineIntel GNU/Linux). What
I'm observing are regular streak of system unreponsiveness. Performance
monitors show an activity of high-nice processes during these periods.
OProfile gives ~24% time eaten by apci_idle_enter_bm() with ACPI enabled and
35% time by mwait_idle() with acpi=off, regardless of streak presence or just
smooth operating time. My question is how can I debug more indepth to see
what's happening and what the named functions do so I can or can't blame them
for unusable system. Thanks in advance.
