Hi,
I'm experiencing frequent kernel panics which can be triggered by
sending the laptop to sleep and waking it up.
The wifi chip is a bcm4331, the driver should be b43, kernel version is
3.12.6, OS is Debian 7.3.
The extract from /var/log/messages is in the end of this email.
Is that something I'm doing wrong? Can I provide any further
information to help fix this?
cheers, lukas
