My laptop frequently (i.e., at least one time in three) crashes
after resuming from a suspend activity. Usually, the problem
is file-system related, and automatic fsck can't cope.
I run fvwm, which creates named pipes and Unix-domain sockets
under /var/tmp (e.g., /var/tmp/FvwmCommand-bigboy.machshav.com:0.0C
is a named pipe; I see Unix-domain sockets in /var/tmp/orbit-smb).
Often -- and I don't know why; I'll be send-pring separately on
this point -- X exits during the resume. The i-nodes for these
"files" are listed as unallocated, or with duplicate blocks. I've
been unable to get a crash dump; when I try, I get things like
page faults during the dump. I suspect, though, that there's data
queued that isn't emptied because of an abnormal exit.
Suspend/resume a bunch of times...
Unknown -- and it's bad enough that I've stopped carrying my
NetBSD laptop on trips.
