Hi, and apologies if this list is an impolite place to ask for help.
(If not, where is better?)
I tried building myself a 2.6.28.7 Linux kernel, but the IDE drivers
seem not to be working. My hard drive is IDE ATA. CONFIG_IDE is
built into the kernel. I've tried both with and without
CONFIG_IDE_GENERIC, but there's not much difference. The root
partition is ext2 and ext2 is built into the kernel (but it looks like
the kernel's not even seeing any drives or partitions.)
On failed 2.6.28.7 boot, I see the following relevant-looking lines.
I copied these by hand, so there might be a minor typo. Yes, the
kernel lists no partitions after "available partitions:".
ide-gd driver 1.18
ide-cd driver 5.00
ide_generic: please use "probe_mask=0x3f" module parameter
...
VFS: Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Below is a grep excerpt from my .config, and then a successful dmesg
from kernel 2.6.17. Can anyone guess what's going wrong?
Many thanks,
