I can offer a me-too but the machine is different.

I am using an old 80386 to test new kernels on. It is an ancient GW2K
with 16 megabyte of RAM and an old UltraStor drive which was from the
pre-IDE days. Here is how hdparm describes what it finds:

Model=UltraStor Ultra-12, FwRev=0.08, SerialNo=
Config={ HardSect NotMFM Fixed DTR>5Mbs TrkOff }
RawCHS=1224/15/34, TrkSize=20880, SectSize=614, ECCbytes=7
BuffType=2(DualPort), BuffSize=32kB, MaxMultSect=8, MultSect=off
DblWordIO=no, maxPIO=0(slow), DMA=no
CurCHS=0/0/0, CurSects=0, LBA=no
IORDY=no, tPIO={min:0,w/IORDY:0}, PIO modes:

I compiled 2.1.78 with the newest 2.7.2.3 of gcc and the latest
binutils. The boot sequence proceeds normally, mounts the ext2 root
filesystem and than complains that it cannot find init.

The 2.0.33 kernel boots and runs flawlesslly. I used it to compile
the 2.1.78 kernel on the said machine.

I will back off to 2.1.74 and see if I can locate a failure point.
