I'm trying to get Gentoo 1.4RC1 installed onto this machine, had to use the 1.2a boot CD because the cpqarray module crashes on load on the LiveCD.

Everything went as expected, thanks to other discussions in this forum I even managed to get GRUB to correctly install on /dev/ida/c0d0/part2 (part1 is the compaq "maintenance partition).

Because the root partition is on the Compaq Array (it's on /dev/ida/c0d0/part6) I compiled cpqarray support into the kernel, but I can't get it to boot. GRUB can launch the kernel, using:

Code:
/boot/bzImage root=/dev/ida/c0d0/part6


but when the kernel is booting, I get the following:
Code:
cpqarray ida/c0d0: blksz=512 nr_blks=53309280
Partition check:
 ida/c0d0: p1 p2 p3 <p5 p6 p7>
 devfs_register(disc): NULL ops, got c02c5ab4 from major table
 devfs_register(part1): NULL ops, got c02c5ab4 from major table
 devfs_register(part2): NULL ops, got c02c5ab4 from major table
 devfs_register(part3): NULL ops, got c02c5ab4 from major table
 devfs_register(part5): NULL ops, got c02c5ab4 from major table
 devfs_register(part6): NULL ops, got c02c5ab4 from major table
 devfs_register(part7): NULL ops, got c02c5ab4 from major table
...
VFS: Cannot open root device "ida/c0d0/part6" or 00:00
Please append a correct "root=" boot option
Kernel Panic: VFS: Unable to mount root fs on 00:00


which seems to suggest that devfs is unable to add the ida/c0d0/* partitions to /dev, which of course would account for the Kernel panic later on during the boot.

root(part6) is an ext3 partition and ext3-support is compiled into the kernel.

Does anybody have any suggestions on how to proceed?

Thanks

A longshot, but how about this post (specifically comment 5) from this thread?

A longshot maybe, but it did the trick!

Thanks.

Code:
/boot/bzImage root=/dev/ida/c0d0p6



Works now...

Great!

Since the other thread started out as a Grub problem, I'm going to lock this one, but leave it under Installing Gentoo.
