Subject: Weirdness with 2.4.20-ck4

So I tried out 2.4.20-ck4 on my server box, which continually leans
towards the experimental because, well, it seems to work fine.

For 13 days, everything was peachy. Then on the 14th morning I wake
up and dhcp3-server is not responding timely, since my laptop
is unable to acquire an IP address automatically. I serial in and
init has gone D and is eating 99.8% of the CPU.

Every single process under init was DEFUNCT!

New processes also were defunct as well, after being started. I guess
bash was somehow not affected when I logged in.

I can't provide a dmesg, since the machine eventually stopped responding
and I had to hard reboot it. But unless I know for sure what's going on
soon, I'll need to move back to a vanilla kernel or perhaps try out
2.4.20aa, without the rest of the 'desktop' tuning stuff that I don't
really make use of.

Sorry I can't give much info, except possibly my .config. You can get it
at http://triplehelix.org/~joshk/linux/config.gz. If this happens again
I'll be sure to get some pstree output logged somewhere. (Would slabinfo
be useful too in this kind of situation?)

Regards
Josh

Using it on a server box? You should reverse patch the desktop tuning (patch
010) at the very least. Your throughput will be higher without that and it
may well be responsible for the hang.

I'm running 2.4.20-rmap15e for now, but I'm quite sure I only had 001,
002, and 003.

001_o1_pe_ll_030206_ck_2.4.20.patch.bz2
002_aavm_030226_ck_2.4.20.patch.bz2
003_rl2_021215_ck.2.4.20.patch.bz2

Regards,
Josh

Ok. Well I don't recommend the rl2 patch, but I would recommend the first two.
