Thanks Roger. I have edited your bug title and description to include the trace from the BUG message and emphasize that a kernel panic occurs too.
** Description changed: - kernel oops at random when running wireless. Machine locks up with - flashing caps-lock. No messages in /var/log. Kernel oops collected by - serial console. + kernel BUG message and then a kernel panic at random when running + wireless. Machine locks up with flashing caps-lock. No messages in + /var/log. Kernel BUG message and panic collected by serial console. - No known trigger other than running wireless, but the oops clearly - identifies the line in the iwlwifi sources where it happens and the oops - can be avoided by running a wired network connection. + No known trigger other than running wireless, but the BUG message + clearly identifies the line in the iwlwifi sources where it happens and + the oops can be avoided by running a wired network connection.
