SubjectLinux-2.4.22

I configured, built and booted Linux-2.4.22. There are
some problems.

(1) `dmesg` fails to read the first part of the buffered
kernel log. I have attached two files, dmesg-20 (normal)
and dmesg-22 (bad). File dmesg-22 is from Linux-2.4.22
and dmesg-20 is from Linux-2.4.20. To save space, I
snip everything after 'NET4'.

(2) The ipx module fails to load with undefined symbols.
This module loads fine in Linux-2.4.20.

depmod: *** Unresolved symbols in /lib/modules/2.4.22/kernel/net/ipx/ipx.o
depmod: unregister_8022_client
depmod: make_EII_client
depmod: register_8022_client
depmod: register_snap_client
depmod: make_8023_client
depmod: destroy_8023_client
depmod: destroy_EII_client
depmod: unregister_snap_client

(3) When umounting the root file-system, the machine usually
hangs. The result is a long `fsck` on the next boot. The problem
seems to be that sendmail doesn't get killed during the `init 0`
sequence. It remains with a file open and the root file-system isn't
unmounted. A temporary work-round is to `ifconfig eth0 down` before
starting shutdown. Otherwise, sendmail remains stuck in the 'D' state.

(4) When mounting the DOS file-systems during startup, the echo
on the screen shows about 15 lines of white-space. This never
happened before. When mounting /proc, there are 6 lines of
white-space, also strange.

none /proc proc defaults 0 2
/dev/sda1 /dos/drive_C msdos defaults 0 2
/dev/sda5 /dos/drive_D msdos defaults 0 2


Otherwise it works. I am using it now so I can test any possible
fixes.
