I don't know if it is related, but I had several other hard freezes in
meantime. One reproducible method is to run xdir (or gftp, works too),
connect to a remote site, wait until the connection is established,
choose "quit" from the menu, confirm, and boom! hard freeze. If I don't
connect to a remote site, there is no freeze. I don't know how to debug
this, because I don't see any error messages.
The other kernel panics arrived at the end of the boot process or during
login. The message was "kernel stack overflow, in swapper task, not
syncing", many lines of "page fault in interrupt handler, addr=c". The
kernel addresses given were all init_task_union + offset.
Another strange thing, or maybe it is related, are error messages in my
Aug 27 12:04:42 rennes-28 dhcpcd: corrupted UDP msg with
uh_ulen=312 in_cksum=-2 discarded

Such messages appear irregularly, about every 10 minutes. There is no
clear relation with the dialog with my dhcp server. Otherwise the net
traffic over ethrnet/adsl/dhcp seems to work correctly.
This happens only with 2.3.15, not with 2.2.12. In the log file I find
that I had such messages also between June 3 and June 13. I think these
were the times when I tried 2.3.x kernels.
