Bugs in 2.1.99

Hello friends,

Here are a few bugs in 2.1.99 I noticed.

a) aic7xxx, Do this:
1. cat /proc/ioports # works fine
2. modprobe -a aic7xxx # works fine
3. cat /proc/ioports # Oops, a region was not released in
# cleanup_module() ?
4. cat /proc/interrupts # another Oops, IRQ 10 was not released?
5. modprobe -a aic7xx # works almost fine,
# i.e. the scsi1 now appears instead of
# scsi0
6. cat /proc/ioports /proc/interrupts # works fine again.

This is a very old bug and is present even in 2.0.32, but in 2.1.99 it
even caused kernel panic when the only device on that aha2940 was a
removable IOMEGA ZIP and it wasn't inserted. The above scenario was with
the cartridge inserted.

b) fdformat /dev/fd0 (dev 2:0) says "Could not determine current format
type: Operation not supported by device".

However, doing fdformat /dev/fd0H1440 (dev 2:28) happily formats the
floppy and then even fdformat /dev/fd0 works as well.

c) This usual pipe hangs:

bzip2 -dc linux-2.1.99.tar.bz2 | tar xvf -

and strace-ing it shows lots of SIGSEGV's sent to bzip2 process.

Thanks for reading,
