I track it down to the diffs to drivers/block/genhd.c from 2.1.115 to
2.1.116, the chunks between lines 400 and 450. It seems to be remapping
the drive geometry if the size is greater than 504M, even if the H/S
portion of the bios C/H/S info is already reasonable. This is from
looking at the diffs - I haven't had a chance to look at the code bursts
side by side yet.

My FUJITSU MPB3064ATU E isn't happy with the results. I know the drive
was set up CHS when I formatted it under 2.1.115 about a week ago.

However, from /var/log/syslog:
