Package: kernel-image-2.4.27-1-sparc64
Version: 2.4.27-1
Severity: normal

Joshua Kwan and I discussed this on IRC.  As I understand it, having
ide-disk configured as a module but the CMD64x IDE controller driver
compiled into the kernel produces a situation where the CMD64x controller
will try to do a partition check of the hard drives connected to
it...before ide-disk is loaded.

This results in the boot process howling with error messages that will
strike terror into people, thusly:

 unable to read partition table

This is not actually a real problem, as the ide-disk module is subsequently
loaded, the partition tables scanned successfully, filesystem checks
performed, and do forth.

But the above output is both ugly and frightening, and may cause our users
to jump to erroneous conclusions.

Josh is already working on this problem but I wanted to go ahead and file
this report so any other users seeing this might find it and know not to
panic (I just about had a heart attack).

My full dmesg log is attached.  Please let me know if you need any more
information.
