I am trying to (remotely) upgrade a kernel 2.2.17 with raid-2.2.17-A0
patch to 2.4.19-rc3 with the little attached patch to get autodetect
to work (sparc64 architecture.) Here is a partial manual transcript
from what appears on the console; the system still boots 2.2.17
without problem. I would be grateful for any advice on getting things
right...
Thanks,
Hein
