The RZ-1000 is a highly buggy chipset, particularly where DMA is
concerned
CONFIG_BLK_DEV_RZ1000:
The PC-Technologies RZ1000 IDE chip is used on many common 486 and
Pentium motherboards, usually along with the "Neptune" chipset.
Unfortunately, it has a rather nasty design flaw that can cause
severe data corruption under many conditions. Say Y here to include
code which automatically detects and corrects the problem under
Linux. This may slow disk throughput by a few percent, but at least
things will operate 100% reliably.
This is enabled in both kernels, but the which drive is not being
seen? (Your failure to mount rootfs looks like a /dev/hda (post
install) problem and it it is a CD problem on install it should be
block major 11 anyway. ) So I assume you can install but not boot.
Have you tried kernel 2.2.19-10mdk included in the distro?
