After boot, automount takes 100% of CPU, according to 'top'. top - 23:41:18 up 9 min, 3 users, load average: 3.06, 2.73, 1.31 Tasks: 140 total, 1 running, 139 sleeping, 0 stopped, 0 zombieCpu(s): 24.3%us, 0.8%sy, 0.0%ni, 74.9%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

Fair enough, but when I 'strace' automount, I just see: # strace -p 2886 Process 2886 attached - interrupt to quit rt_sigtimedwait(~[CHLD CONT RTMIN RT_1], (and it just hangs there).While 'strace' is hanging, automount is still (according to top at least) consuming 100% CPU. I tried thinking about threads, but it seems like automount is just a single thread from what I can tell.
Any ideas? # uname -aLinux amd 2.6.23-0.139.rc3.git10.fc8 #1 SMP Sun Aug 26 19:23:52 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux
BTW, I'm using the previous kernel above, because the latest kernel 2.6.23-0.185.rc6.git7 seemed to be causing the machine to power-off under load, which I guess might indicate a hardware problem although the machine has not suffered hardware problems up til now. In any case could hardware cause the strangeness above?
BTW#2, I stopped the autofs service and automount went away -- I never use automount anyhow.
