Thomas, I had the same problem, so that "brokenmodules=" works I did the
following :

Change INIRD_MODULES in /etc/sysconfig/kernel

rob@oak:/etc/sysconfig> grep INITRD kernel
#INITRD_MODULES="processor thermal pata_amd pata_pdc202xx_old fan reiserfs edd"
INITRD_MODULES="processor thermal pata_amd pdc202xx_old fan reiserfs edd"

Created a new initrd with mkinitrd (appending _pata_pdc202xx_old to saved
original).

Updated GRUB entry to add brokenmodules to boot line.

You may have to alter /etc/fstab when /dev/sdX become /dev/hdY, but I use
partition labels and a line like :

LABEL=OS10.3-Work /work ext3 data=writeback,noacl 1 2

So my mounts are not reliant on device names.


Upstream - AC responded to my "me too" with info and then a patch

Am testing Alan Cox's patch to 2.6.24-rc3-mm1, enabling burstmode looks hopeful
on my box. I've had iostat 20,000+ Blk_wrtn with pata_pdc202xx_old, whilst
running bonnie++.


But I never actually saw crashes, just very slow operation, that might be due
to chipset differences, but it might possibly be that we have different bugs.
Also strictly I ought to have reproduced the "resetting link" errors without
the burstmode patch first to prove that is teh real solution (not some of the
other many changes in -rc3-mm1).
