HI there,

I did a anoncvs on my machine to rebuild the kernel and source
but after downloading updated sources, I recompile the new kernel
with the steps given and when I reboot the machine
it went into debug mode where it ask me to do either trace or ps .
I couldn't copy the output to include it here.

How can I revert back to the old kernel ?

Assuming you followed all the instructions, try this at the boot prompt:

boot> boot -a
boot> boot wd0a/bsd.old

That's off the top of my head & could be a little bit off, but that's the general idea. Obviously, use sd0a with a SCSI disk, etc.

Or is there a way
for me to still run the new kernel ?

Doesn't sound like it.

Your help is much appreciated..

Hope it helps,
-Kit
