When I pull the main cord whilst the machine is running, it continues to operate for 1-3 secs on battery power and then hangs/locks solid. After a reboot ... there's nothing obvious in the logs. This problem does not occur on 2.4 (I've tried all the way up to 2.4.22-bk27) and does not happen <= 2.5.56. I've had a look at the change log for 2.5.57 and through the patch for obvious things ... but nothing stands out. Can anybody help me with this / suggest a plan of attack to narrow the problem down? TIA Daveh (Please CC me at on answers as I'm not currently subscribed to the mailing list)
