Yeah, that has me baffled too. Still, the fact is that I can only trigger the bug by loading sym53c8xx before sungem. I have yet to find any other conditions that trigger it. Loading sungem before sym53c8xx on an affected kernel gives no trouble at all. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
