Description neurosys 2000-09-24 19:30:00 UTC 
While a user with a shell was connected to my system. We engaged in a talk session and in the middle of the talk session i got this error...

Fatal Trap 12: page fault while in kernel mode
fault virtual address    = 0xc076e000
fault code               = supervisor read, page not present
instructor pointer       = 0x8:0xc019a51d

frame pointer            = 0x10:0xc02a3fb4
code segment             = base rx0, limit 0xfffff, type 0x1b
                         = DPL 0, pres 1, def32 1, gran 1
processor eflags         = interrupt enabled, resume, IOPL = 0
current process          = Idle
interrupt mask           =
trap number              = 12
panic = page fault

Then it says reboot in 15 secs or press any key to abort. I pressed the space bar, it said after that "press any key to reboot" and wrote the problem down on paper. I pressed anykey, it rebooted without dismounting the drives and rebooted. This is the 3rd time it happend with the same error in Talk.

How-To-Repeat: use Talk. No specific time period, all under 10 mins.

Quite franky, this report is useless without *a lot* more information. 
Furthermore, I can't reproduce this.  If this is still a problem in 4.3, 
please file another PR.
