Re: Problem compiling 2.6.26 kernel

I have used Debian for many years and I have always used the

After I do the "make-kpkg --revision= ## kernel-image" and then use
"dpkg -i" to install the new kernel, I keep getting a kernel panic. The
message reads like this:
VFS: Cannot open rootdevice "301" or unknown-block(3,1)
Please append a correct "root=" boot option; here are available
partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(3,1)
It appears to have trouble mounting the file systems. I've never run
into this before. The boot manager is still "lilo" and there is a
"root=/dev/hda1" statement in the "lilo.conf" file. Any suggestions
would be appreciated. Thanks.
You seem to be the second person in two days who has complained about
this. Has kernel.org changed how IDE devices are accessed?
For the time being, you can probably boot using a root of /dev/sda1. The
problem is probably that the kernel IDE driver (CONFIG_BLK_DEV_IDE) is
not being loaded before libata (CONFIG_ATA). I'm running 2.6.26.5 with a
config file that I've used for about a year; I generally get my kernels
from kernel.org.
It would be interesting to know where your kernel source comes from.
Also, please give us the output of these commands:
grep BLK_DEV_IDE .config
grep "CONFIG_S\?ATA" .config
BTW, I have both BLK_DEV_IDE and BLK_DEV_IDEDISK set to "y".
