Package: network-manager
Version: 0.8.1-6+squeeze1
Severity: important
File: /usr/sbin/NetworkManager
Hello,
I'm seeing frequent (about once per day) crashes of NetworkManager.
syslog of the last crash is attached. It seems to me that this specific crash
has happened while switching from mobile network to wifi, but I have a feeling
crashes have happened at other occasions as well.
I've got syslog records back to Feb 28, but the first occurrence of the issue is Mar 15.
On Mar 11, I had switched to Linux 2.6.32-31 while I had been running 2.6.32-30 before.
I guess it's time to reboot into 2.6.32-32...
BTW: Where can one find the backtrace that syslog says is generated?
Kind regards,
Thiemo
P.S.: Just to give you an impression on the frequency of the crashes:
