Hi All,
I'd reported a disaster with 2.4.14+preempt, but I have just reproduced it with 2.4.14 vanilla - (to recap, "dbench 16" hangs the system hard, it doesn't even respond to pings, and must be power cycled)
Again, since I am seeing the problem with 2.4.14 vanilla, the preempt patch is NOT at fault here -
However I am concerned with this latest twist, as I want linux to be extremely stable, and this sort of thing is discouraging.
I think there may be a problem with the compaq smart/2p raid drivers, since the "do_ida_intr" code keeps showing up in the oops, and I have not seen a problem with 2.4.14 on any other system.
I am going to try and reproduce the oops elsewhere, and hopefuly I will not be able to - in any event, the oops follows:
Compaq 6500 4XPPRO 200 1.2 GB RAM compaq "smart" raid controller
