Description William Tetrault 2004-03-08 17:32:38 UTC

panic occurs regardless of setting limit e.g. bs=1K or bs=1M or leave it blank; motherboard is MSI K8T Neo; SMART is disabled in BIOS (but happens whether enabled or not); boot was normal - used "gentoo-nofb"; last line of panic msg references the interrupt handler.

Reproducible: Always
Steps to Reproduce:
1.type "dd if=/dev/zero of=/dev/hda";
2.hit "enter";
3.wait 2-3 seconds.

Actual Results:  
the kernel panicked.

Expected Results:  
written zeroes to the hard drive, in the case /dev/hda

Comment 1 Brad House 2004-03-09 20:31:39 UTC

most likely this has to do with cpu errata #93
try passing 
gentoo-nofb idle=poll
at the isolinux prompt and see if that helps.
There's a workaround in the current kernel for errata #93,
but it doesn't always work.  The real solution is to bug your
bios manufacturer to fix errata #93.

since it is upstream, closing
