It's from my previous experience from 2001 I guess; I know for sure
replacing r4k-ip22 with r5k-ip22 cured the problem previously, just
can't find any reference, I guess it was a tip received on irc.

Nothing in /var/log/dmesg*

No, first I experienced the problem during a dist-upgrade w/
2.6.26-2-r4k-ip22, still logged in via ssh sitting downstairs on my
teras; when I came back to the Indy's console for booting the new
kernel I noticed a full screen titled 'you have found a kernel bug
#7'. Hoping this will disappear with the new kernel and
openssh-server being configured I rebooted to the current kernel,
sadly only with partial success:
- no more kernel errors on screen
- openssh-server still fails to configure (one of ssh-keygen's
friends segfaulting.)
I'm attaching the recording from "2>&1 gdb ssh | tee gdb_ssh"
You almost convinced me the problem is not kernel related and
searching the archives of debian mips yielded a message from
Martin Michlmayr <t...@cyrius.com>
http://lists.debian.org/debian-mips/2008/03/msg00039.html
stating that r4k-ip22 are running on r5k-ip22 machines too.
You may close the bug for now, I'll investigate further and reopen and
reassign it: living w/o a working sshd on that machine isn't really an
option.
Thanks for caring
Siggy
