Public bug reported:
Binary package hint: network-manager
Just installed Feisty on my iBook G4 and upgraded to Gutsy (using
update-manager).
Using Feisty, network-manager worked fine with both my wired and
wireless (bcm43xx) connection. After upgrading to Gutsy (network-manager
0.6.5-0ubuntu16), NetworkManager process takes 100% CPU and nm-applet
shows no device and disconnected status. Using "htop", I straced
NetworkManager and found this:
...
sigreturn() = ? (mask now [ILL TRAP ABRT BUS FPE
USR1 USR2 PIPE ALRM TERM STKFLT CONT STOP IO])
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
sigreturn() = ? (mask now [ILL TRAP ABRT BUS FPE
USR1 USR2 PIPE ALRM TERM STKFLT CONT STOP IO])
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
sigreturn() = ? (mask now [ILL TRAP ABRT BUS FPE
USR1 USR2 PIPE ALRM TERM STKFLT CONT STOP IO])
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
sigreturn() = ? (mask now [ILL TRAP ABRT BUS FPE
USR1 USR2 PIPE ALRM TERM STKFLT CONT STOP IO])
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
...
So, I killed it (SIGKILL) and straced it from the beginning, I'll attach
the log.
If I rmmod bcm43xx and restart network manager with
/etc/dbus-1/event.d/25NetworkManager restart, everything seems to work
fine, but if I modprobe bcm43xx again (without restarting nm), the CPU
goes 100% again and this is shown on syslog:
