I have tracked it down and found that the problem was introduced with
version 2.1.95. Luckily, it is by far the smallest patch in a long row,
so I could take a closer look at it.

It is the two lines changed in drivers/block/ll_rw_blk.c
After undoing the change, 2.1.95 worked fine for me. Unluckily, if I do
the same in 2.1.101, it breaks even earlier -- when first accessing the
hard disk. It gets as far as

Partition check:


I don't think the problem is very hardware specific. I tried it on my
Cyrix-6x86 (no, it's not a heating problem -- it got quite warm while
compiling all these kernels, though :-) and on my brother's 486. Both
show exactly the same problem -- they hang as soon as I try to use a
loopback device connected to a file that's not on the root file system.
