urgh, i take that back. During an I/O-heavy operation (mpd rebuilding
its index to a filesystem stored on a 2GB USB flash drive), the machine
became unresponsive. i'm hooked into the serial console, and i see
messages about blocked tasks for more than 120 seconds.
I used the magic SysRq to dump blocked processes to the console. [0]
the attached log shows two warnings about blocked processes for 120
seconds, followed by the output of my SysRq call.
Let me know if there's other debugging you'd like me to try. The
machine is still in this state, and i've got the console attached.
Regards,
--dkg
[0] I use "screen /dev/ttyUSB0 115200" to connect to the console. so i
sent the sysrq-W command with: <Ctrl-a> <b> <w>
