... Yesterday, my
system froze twice, i.e. became completely unresponsive, the caps lock
LED flashing, as it does on this machine when it's frozen. (A quick
Google search suggests that's a sign of kernel panic.) The only
remedy is to hold down the power button until it powers down. The
reason I suspect Network-Manager is twofold: (1) the freeze only
happened when I had the machine hard-wired to my network, and (2)
syslog showed lots of wlan0 activity - trying to connect, being denied
a DHCP address - just before the freeze occurs. Has anyone else had a
similar experience? I don't want to file a bug report against
Network-Manager unless I'm pretty sure it's the culprit.
