Here is a list of problems I encountered with 2.3.22 after 5 minutes
with it:
Just booted freshly compiled 2.3.22, started ppp session to my ISP,
and did some work over ssh. After I closed ssh connection,
immediatelly 10 messages 'mordor:~$ Use "logout" to leave the shell.'
appeared followed by 'mordor:~$ logout'. (mordor is my home box)
And no login promt there. "WTF", I thought. switched to another
vt console and tried to duwn ppp link. but get no prompt back from shell,
after 'ppp-off'. switched new console, pressed several keys and it hungs
too... and all consoles did that (except ones where syslogd writes its
output). After some console switching I found that I'm running
procinfo on one of them. It was dead also, but last value it printed was
somewhat interesting. It said that I have 3 running of -905068 processes.
Well. I decided to umount my disks and pressed SysRQ-U, immediattely followed
by bunch of oopses and spontaneous reboot. Disks was not properly umounted.
Well. After reboot I decided to try to reproduce problem.
I did slogin localhost. This action was followed by another bunch of oopses
(none of these oopses was logged) and another reboot.
After reboot I tried 'slogin localhost' again and again and it worked.
Hmm... I decided to reboot and guess what? I got oops in init after
message about umounting local filesystems.
I will try various things later and if something will come up, I report
it too.
This is Pentium-166, 32M RAM. all kernels between 2.3.0 and 2.3.20
inclusively was fine here. I have not tried 2.3.21.
PS: After unsuccesful attempt to send this mail I found that if I do
'killall any_prog', no matter which prog I want to kill, shell behaves
as if it gets bunch of ^D charasters and if console switching works
(it works aometimes and sometimes not), than procinfo shows negative
number of total processes in system which is quickly decreases
(e.g. it got from near -40000 to -60000 in several seconds)
Here is my dmesg output from 2.3.22:
