Known problems for 3.5/0.5 virtual space split???

Known problems for 3.5/0.5 virtual space split???

[gigag]

I wonder if there are any known problems for applying 
2.4.21rc8aa1 patch from Andrea?

I'm trying to boot a Xeon 2.4 box with 4GB of RAM, IDE CD and 
Adaptec AIC7XXX SCSI devices.

I compile the kernel with 1/3 split and it boots OK. When I simply 
change the split to 3.5/0.5, it gets stuck during the boot not being 
able to mount root partition.

Any ideas? Any other working kernel/patch configurations for h/w 
like I have?

Thanks
Giga

Odd - should work. Post a boot log (use a serial console).

Also, if you can try 2.5-mjb tree, that should have a forward port of
the same concept ... does it work there?

Yes, it worked with 2.5.70 kernel with the proper mjb patch. I had 
to change root=LABEL=/ token to root=/dev/sda2 one in order to 
make the system boot from SCSI disk. Also, I compiled AIC7XXX 
drivers statically into the kernel.

I tried to do the same trick for 2.4.21 kernel, but it seemed not to 
help. I didn't play with it for too long though. I indend to experiment 
with 2.4.21 kernel in about a week after I finish with 2.5.70, which 
is currently working for me.

Thanks a lot for the help
