-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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 Jan 14 09:43:26 debianPro kernel: [10740.497028] PM: Syncing filesystems ... done.
