Hi!
When I boot by server (Siemens Primergy 500 / 4xPPro 200 / aic7xxx / Mylex
DAC 960PD(not used) / 256MB RAM) using the kernel (2.4.0-test8 or 2.3.9) from
sda1, it boots up correctly, telling me that runlevel 2 has been reached and
starts reporting:
Unable to handle kernel NULL pointer dereference at virtual address 00000034
printing eip:
c01542ab
*pde = 00000000

pid: # (changing from pid to pid)

/sbin/mingetty is the same size as on my working box (also Kernel 2.3.9) also
I didn't touch it till the installation. Even after copying the working mingetty
to the not-working box doesn't help.

I really dont't know what to do now and I really need the box up and running.

Thanks for any help,
Sebastian

PS: If I boot using the (SuSE) installation disk (loading the modules manually,
letting him use /dev/sda1 as root device, everything works okay.
