kernel oops when mounting external drive

[Nobody's Hero]

I have a 200 GB IDE drive that I formated to ext2 in my desktop. I just bought an external combo enclosure (firewire/usb2). I mounted it just fine earlier as a firewire device. Now, I just tried it again and I got a Kernel oops.

1) Any ideas why?

2) Do I need to do anything after a kernel oops, other than xrefresh :) ?

here's the dump from dmesg:

First off, is this an Intel machine? From the oops, it sure looks like a Mac of some sort (esp. comments about "altivec")? Not that that necessarily matters, but it might...

Oops: machine check, sig: 7 Looks like some issue with the hardware? The "machine check" stuff, at least in Intel boxes, is there to do some basic sanity checks on the processor -- stuff like "is the voltage OK?", "is the temp. OK?". If one of these tests fails, and the OS has set up a machine check interrupt handler, then that handler gets called and the OS can decide what to do with the error. Perhaps the Mac equivalent is similar? Check the power and/or the temperature, I guess... or google for "machine check" and your processor.

I figured most of this stuff was platform independent, but if it matters...


It's an 800 MHz iBook. The IDE drive was formatted in a desktop (x86) running Red Hat 8.0 pretty much stock. The iBook is running Yellow Dog Linux 3.0 (which is just redhat compiled for PPC) with kernel 2.4.20-ben8 with a few modifications.

I'll see what searching G4L tells me about machine check. There was so much text I didn't even know which lines were the important ones to search for :) Thanks!
