>Description:
After upgrading src to sources from Oct 10th, I cannot boot my
powerpc64 machine any longer. The kernel panics during boot while,
it seems, initializing the ATA device.
Things work fine with the kernel details shown above (Oct 8th) but
fail with a kernel from Oct 10th and also with a fresh kernel from
today.
The copy/pasted message I see is the following. Please excuse any
typos as I had to get this from a very bad-quality picture I took
from the screen right before the machine rebooted on its own...
