much loss of quality on linux? Tried some, couldn't crop images
easily!

Did some other previous kernel versions work/boot for you?
With the same config file?

Yep, till September 2006 I was active with Kernel building with
another group in my Labs. I think I have built 2.6.18 sucessfully for
my IBM ThinkCentre A51 Workstation (Non HT) that time. Should I post
that .config here?

Now I have resumed Kernel building activities after a gap....all hell
broke loose for me....problems are cropping up with this P4-HT
machine!

I have compared my present .config with the distro's updated 2.6.18
kernel config, made changes. No differences. But I really wonder
what's wrong with my 2.6.19/2.6.20-rc4 building efforts :( I still
have one my Dual Core Laptop in the que, god knows...


It looks like your new kernel doesn't have a driver for the boot
device, or the initrd does not have that driver.

Is there any way to check that? My lspci data:
