>Description:
      After the build of an updated kernel (and 'world') with the almost the
same kernel-config-file (just commented out the IPFILTER option, as there
were compile errors resolved by doing so), now the system crashes in a
kernel panic after *exactly* 1h0m15s uptime. This time is stable and
reproduceable; the panic occurs guaranteed after exactly that time.
(This is the uptime shown by the kernel, the 'top' command shows 1h0m31s).

      The message on the panic screen: Fatal trap 12: page fault while in
kernel mode; fault virtual address =0x8; fault code= supervisor read, page
not present; [...] code segment = base 0x0, limit 0xfffff, type 0x1b, DPL
0, pres 1, def32 1, gran 1; processor eflags = interrupt enabled, resume,
IOPL = 0; current process = 27 (swi8: tty: sio clock); trap number = 12

       As the process pretty much sounds like something time related, I
assume it must come from that routines. 

       The problem is the very same on a different mainboard (just plugged
the HDD to another piece of hardware). The kernel-boot messages do not
contain any errors about faulty hardware (running the usual hardware A
or hardware B which I used to verify if I have a mainboard problem). Say:
I think I can clearly state: there's a software issue.

>How-To-Repeat:
      Just have a cup of tee and wait 1h0m15s :-)

      Seriously: If it's a config-related issue, then I'd gladly apreciate
any infomation, which enables me to fix this. I'm not kernel hacker, but
I run a 'home grown' one, as I need to enable some ISDN hardware.

      If you want to have a look at the config files, then just drop me
a message; as well I can test rebuild in order to identify this problem.
Thanks.
