Details vary, of course, but the stack trace is pretty much the same always.
The system is running a custom 2.4.17 kernel, the only substantial
differences from the stock 686-smp kernel are CONFIG_HIGHMEM4G=y and
CONFIG_MPENTIUMIII=y.
I am about to upgrade to a similar 2.4.18 kernel, and will report as to
whether I see this happen again (could take a few days).
