Hi all,
My -STABLE machine blew up last night, about 3 hours into compiling
OpenOffice. I wasn't awake at the time, so I don't know exactly what
happened other than that I came in this morning to find a rebooted machine
and a crash dump. It happened around 2am - there might have been a mail
synchronisation going on at the same time, but nothing much else.
>From the comments in ffs_alloc.c it seems that there were no free blocks
anywhere in a particular cylinder group, although there presumably should
have been. I don't know enough about FFS to know if this is really a bug,
or a sign of some corruption in my filesystem that I should attend to.
The same machine locked up a couple of times last weekend - one when
compiling some part of KDE, then when encoding some MP3s. No panic for
either of these, just a hard lock. We were having a micro-heatwave here
that weekend so I figured it was a cooling problem I should look at before
the summer really got going.
Stack trace and dmesg attached. Machine is running -STABLE from last
Tuesday:
