Got 2.4.20 to compile/run, but get NULL pointer dereference under load.
With a combo of egcs64 and gcc 2.95 I managed to get a kernel compiled which
had all the hardware/drivers I needed. (differential SCSI, SMP, RAID)
With some simple testing on a pair of RAID0 drives (in a D1000) using cp -a
I get:
Unable to handle kernel NULL pointer dereference
tsk->{mm,active_mm}->context = 00000000000004d0
tsk->{mm,active_mm}->pgd = fffff800779d2000

Is there a problem with my hardware, the 2.4 series kernel, my compile?
