2.1.24 problems.

2.1.24 compiles OK - still a few problems though
Most importantly - I can't get any modules to load after sound.o is loaded
- insmod oopses (see below). I suppose that'll be fixed when Hannu
releases the updated driver (still ETA Monday?)

If I were to use the sound driver, I'd still have had to put in
#ifndef __SMP__ around the IRQ detection code, as the code still doesn't
detect IRQs properly under SMP. The patch I posted a couple of weeks ago
still goes in OK.

NFS still doesn't work as a module - kernel_flag and
active_kernel_processor are undefined - I don't know why they heven't got
versions in nfs.o - they have in the kernel. Odd.

Also, I'm still getting the following:

klogd 1.3-3, log source = /proc/kmsg started.
Loaded 4041 symbols from /usr/src/Linux/System.map.
Symbols match kernel version 2.1.24.
Error seeking in /dev/kmem
Error adding kernel module table entry.

Any ideas about it would be welcome.

Also, a lot of programs are complaining:
xntpd[164]: select() error: error 514
inetd[175]: select: Unknown error 514
lpd[241]: select: Unknown error 514
syslogd: select: error 514

and, by way of a change:
rwhod[294]: recv: Unknown error 512
mountd[190]: Ack! Gack! svc_run returned!
nfsd[199]: Oh no Mr. Bill... nfs_server() returned!

What's the fix for the select errors? I've upgraded to libc-5.4.21 in the
vain hope that it'd help, but no joy. Do we just have to wait for new
versions of everything to come out?

System has 2.1.24/SMP, gcc-, binutils-, modutils-2.1.23,
libc-5.4.21, anything else you want to know on request.
