When rebooting (halt works fine) a Compaq Workstation AP200, right before restart the monitor looses the signal, the computer stops. Have to press the power button, ctrl-alt-del doesn't work either here. This worked fine in beta3. Might be related to #23322 (this problem is resolved in beta4).
Can you try the lilo / append option "apm=realmode"? that should restore the beta3 behavior
No, that doesn't help. I' almost sure this worked in B3 (you say it should work. Therefore I'm feeling somewhat unsure; I tested B3 on that computer some days - dont't think I didn't try a reboot, only halts, that would be very untypical for me - I hardly ever use halt)- should I grab the B3 copy and try it again? Just in case ...
Could you try the suggestions for the kernel options as mentioned on bug 26444? This looks like a duplicate of that. *** This bug has been marked as a duplicate of 26444 ***
