Description paluch 1999-12-12 12:37:22 UTC 
RedHat 6.0 kernel causes early panic on AlphaServer 2100 (Sable) 4/275
with 2 CPU's 21064, NCR SCSI, 192MB RAM, boot from SRM console.
Symptomps:
original non-smp kernel:
    when aboot finishes kernel load it says 'CPU 0 halted' and stops.
kernel-smp.img from errata:
    lots of panics right after hardware detection.

RedHat 5.2 works fine (2.0.35 kernel - sable-s.img).

Seems to be fixed in 2.2.14 and later kernels.
Howerver  kernel option 'PCI Quirks = Yes' needed to detect SCSI in such SMP
kernels (tested
2.2.14 and 2.2.16)

I assume that you're now using 6.2/7.0 by now and this is no longer a problem
