Subject : 2.6.29-rc5+: usb bluetooth crashes system Submitter : Pavel Machek <pavel@ucw.cz> Date : 2009-03-10 11:23 References : http://marc.info/?l=linux-kernel&m=123668450400940&w=4 Notify-Also : Greg KH <greg@kroah.com> This entry is being used for tracking a regression from 2.6.28. Please don't close it until the problem is fixed in the mainline.
Ok, more info: It works ok in 2.6.28. It is repeatable by both ^c-ing the pppd or pressing red key on telephone to terminate the connection. Machine dies a brief moment after disconnect; "connection terminated" still gets to the log. It happened many times in X; sometimes I see keyboard LEDs panic blink, sometimes not. When repeated on the console, I get BUG: spinlock bad magic on CPU#0, swapper/0 (and hard hang).
