Description Magnus Johansson 2002-12-30 15:52:22 UTC
Description of problem:
The SMP-version of the kernel oopses every time i try to start it. The UP-kernel
works fine. Various 7.1 and 7.2 smp-kernels (including errata) have worked fine
on the same hardware.

This is the message on the screen.

does this get fixed if you use "acpi=off" ?

Comment 2 Magnus Johansson 2002-12-30 17:04:28 UTC
Yes, the SMP-kernel now boots up fine. For a beta-release we're now OK, this
issue can be closed.

Please attach the output of 'dmidecode' from the kernel-utils package on your

Comment 5 Magnus Johansson 2003-01-01 14:49:39 UTC
I ran successfully a test with Memtest86 3.0 on the hardware. I should also
mention that this test-machine has also successfully run Solaris 8 and FreeBSD
4.7 UP.

The reason that I mention this is that I get both SMP and UP kernel oops (with
acpi=off, obviously) when I have httpd started during boot-up, which was a big
surprise. If I start httpd from a Gnome-terminal, the kernel doesn't Oops, but
httpd goes into infinite 99.9% CPU consumption. 
Unfortunately it is difficult to get good Oops messages for this. Sometimes the
screen just goes black, sometimes the messages are reported very fast in an
infinite loop. Should this be reported as a separate error?
