Public bug reported: During use, X randomly crashes and restarts. This does not seem to be related to anything the user is doing at the time. Syslog indicates some interesting things happening with the bcm5974 driver when the crash occurs. However, the same behavior also often occurs without resulting in a crash. In the attached log files, the crash occurred at 09:41:29.
This is what syslog looks like: Sep 1 09:41:00 igor-mbp kernel: [375971.850127] usb 7-2: new full speed USB device using uhci_hcd and address 47 Sep 1 09:41:00 igor-mbp kernel: [375972.100371] input: Apple, Inc.
