That does not cause the problem per se. It seems manufacturers of hdds,
particularly ides, discovered that the broad tolerances allowed by most
software made it possible to relax QA and sell out of spec drives. Now with
their newer ATA/66 and ATA/100 tech, they are supplying drivers that are very
tolerant, but the linux-ide folks BELIEVED the specs and wrote with that
target.
The fix is to hit F1 at the splash screen and type
expert linux idebus=33
--just a workaround.... Of course avoid selecting hd optimisation and put an
idebus=33 in the append statement blank of every single bootable linux on the
system.
You can alter this, once you are up, by patching /etc/rc.sysinit with hdparm
statements right after the paths are defined (somewhere in the first 10
lines) that slow down the suspect disks.
Mostly this has been WD disks but some others have also failed. And at least
one has been reported to fail on kernel 2.4.0.... This appears to be a
hardware problem as well because plain vanilla unpatched 2.4 is showing write
errors on some DMA 33 drives where plain 2.2.18 kernel-linus did not.
The fix this time probably has to be to start returning out of spec
merchandise. It might be possible for two kernels to be on your boot menu,
one for good hardware and one for garbage, but they might be for different
versions of the distro, or have other services changed.
It should(tm) be possible to simply replace a 7.2 kernel with 7.1's version
or to use the kernel-linus shipped with 7.2 For the method to do that,

Only the portion relating to the copying of kernel info to /boot need concern
you.
