[64studio-devel] kernel-2.6.22 upsets yaird on hdb

[tim hall]

Hi all,

I just moved my old hard-drive to a new box, so I put it on /dev/hdb
Trying to boot the 2.6.22 kernel seems to upset yaird AFAICT

As well as this:

Probing IDE interface ide1...

Which was there before and didn't prevent booting
I get lots of
waiting for /sys/block/dev/hdb/ to show up
messages
ending in a kernel panic

Having googled a bit, this bug is present in the 2.6.14 kernels as well 
as the 2.6.22 specifically and appears to be some conflict with yaird.

This is admittedly a corner case, but I can easily test future kernels 
against this. It just strengthens the case for getting a new version 
ready for testing. ;)

Anyway, I'm running 2.6.21 for now & I'll check out 2.6.23 as soon as I 
have the rest of my hardware running happily on the old kernel.

cheers,
