It looks like i seldom have luck on installing pre-compiled kernel
provided by debian.. This time again.
What does this error mean?

Nevertheless, i extract the config file from it, and is being compiled
it now. This config seems including way too much staffs, the compilation
takes more than *two hours*...
And, when rebooting the new kernel fails at:
,----
| VFS: Cannot open root device "hdc4" on unknown block (0, 0)
| Please append a correct "root=" boot option
| Kernel panic, not syncing:
| VFS: unable to moiunt root fs on unknown block (0, 0)

Above these lines, i notice that the new kernel has tagged ATA hard disk
as /dev/hda. So this seems to be the problem.
While, my current partition table is:

It's a bit weird that the ATA hard disk has been tagged as /dev/hdc
since the first time installation of debian by cdrom. But later i always
upgrade linux kernel by hand, and without much problem up to 2.6.15.
To solve the kernel panic, i tried appending "root=" option on yaboot,
,----
| vmlinux root=/dev/hda4
`----
But it still causes similar error. :(

They are all okay, AFAIK.

Eli and Bessie went to sleep.
In the middle of the night, Bessie nudged Eli.
"Please be so kindly and close the window. It's cold outside!"
Half asleep, Eli murmured,
"Nu ... so if I'll close the window, will it be warm outside?"
