There's a decent chance mjg59 will ask for more info, so you might file the bug and then give it some time before going through with the fix. Once fixed you may have to break it again to acquire any requested debug info. Your case might be an edge case, but it could affect piles of users. Actually, worth a shot booting off any install/rescue media, without making any changes: dmesg | grep DMI That'll supply make/model and firmware revision. You might check if the firmware is current. But in any case include this line in the bug report. -- Chris Murphy -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@xxxxxxxxxxxxxxxxxxxxxxx
