Shall e-mail you rightway, thanks.
OffTopic: pic was 145KB, any good tool to compress with ease without
much loss of quality on linux? Tried some, couldn't crop images
easily!

Couldn't you just gzip or bzip2 it?

Anyway, it's now available at

for others to make suggestions on.


Error messages:

mount: could not find file system '/dev/root'

setuproot: error mountng /proc : No such file or directory
setuproot: error mountng /sys : No such file or directory
switchroot: mount failed: No such file or directory

Could you please give a pointer on this panic? I did refer to gdb to
debug, it didn't help much. Any clues here how to proceed from here?

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:
