Kernal Panic
After reading all the great reviews of SuperDuper! I thought I'd give it a try. Unfortunately, every time I use it to duplicate a disk it ends in a Kernal Panic. At first I thought it might be a bug in 10.3.4, so I upgraded to 10.3.7, but the same thing happens. It seems to happen AFTER the backup is complete. That is, I think it does successfully duplicate the drive - but then my computer crashes when it is done. This does not happen to me when I duplicate a drive using DiskUtility or CarbonCopyCloner - it seems to be specific to SuperDuper! and it is reproducible every time I run a backup. I have included the log file from my last backup below.

Hi, Luhmann. I know it sounds like an 'excuse', but SuperDuper! does not run anywhere near the Kernel level, so it's not the reason your system is Kernel Panicing. Rather, something else on your system is being triggered by SuperDuper!'s rather fast access of your I/O subsystem. The question is: what's really crashing?
It's difficult for me to know from the SuperDuper!.log, because it doesn't have any information about other programs in it. However, 9 times out of 10, this kind of kernel panic is due to a low-level kernel extension that's trapping I/O -- usually, it's Norton AntiVirus, Norton Utilities, or something similar. (If you've got NAV, turn auto-protect off: it can't handle scanning hundreds of thousands of files at one time without crashing...) If you'll include your panic.log -- which you'll find in /Library/Logs (off the top of your boot volume), it will hopefully point to the culprit. Thanks! |
I don't use Norton or any anti-virus software.
Interestingly, the Panic.log file doesn't show any activity from yesterday. But I'm pretty sure it qualifies as a Kernal Panic when the screen gives you that greyed out look and a box appears telling you to hold down the power button to restart your computer. Could it be some kind of Firewire related bug? Here is a list of my "startup items" Palm Transport Monitor Quicksilver Weathermenu iCalAlarm Scheduler FUS++ ShadowClipboard iTunes Helper That's it. They've never given me problems. |
It could definitely be some kind of Firewire related bug.
Let's do this: generate a System Profiler report with the drive attached. Save it (with File | Save) to the default (XML) format, and send it to support at shirt-pocket dot com (don't attach it here), along with the panic log. I'll take a look and reply, and we can post a summary up here to not leave the thread hanging. Sound reasonable? |
Will do! Thanks.
