Netra X1 strange lock up Debian 3.1, kernel 2.6.12.3
I'm getting a wierd partial-lockup under Debian 3.1 (sarge) on a Netra X1
with a 2.6.11.3 kernel compiled fresh from the sources.
The system will run fine for several weeks. Then it will refuse to run new
shells. Running daemons will continue to run but an attempt to start a new
shell will fail. I put some echos in /etc/profile to see where it stops.
The login stops responding when running the "id -u" command in /etc/profile.
When I remove that command it makes it to the end of /etc/profile but never
starts $HOME/.profile.
The other symptom is that the system clock jumps forward by 3 days, 6 hours,
11 minutes and 15 seconds. Every time. NTP is not running, nor is anything
else that should modify the date.
Examples from the /var/log/messages:

So, the hard drive is still writing. The Bind daemon (named) continues to run
and respond to queries. That and ssh are the only network services I have
running on the box. The kernel continues to output log messages from
iptables (with the wrong date) but outputs no other messages. Ssh will
connect, but it may or may not get past public key authentication. The
console will accept a login and make it past /etc/profile, but never
makes it to a prompt.

I had the same problem with a 2.6.11.7 kernel, also compiled fresh from the
source on kernel.org. I havn't tried the stock Sarge kernel; that's next on my
list.
Has anyone seen anything like this before? Any suggestions for what to try to
track down the problem?
Thanks in advance,
Bill Herrin
