Public bug reported: After the update today (2011/09/18), if I have by broadcom wireless enabled then, after a minute or so of uptime, anything which touches the network will get deadlocked in in the kernel, with rtnl_lock near the top of the kernel stack. This includes everything from firefox and evolution, to "ip addr" and even "sudo", which obviously makes the system nearly unusable. This also prevented "stop network-manager" from returning.
This doesn't seem to be directly a kernel problem - the 3.0.0-8-generic kernel was working fine up until today, and I've also tried the 3.0.0-7-generic kernel which also worked; the same issue occurs. Syslog attached.
