Unable to boot 2.6.0-test1-mm2 (mm1 is OK) on RH 9.0.93 (Severn)

Unable to boot 2.6.0-test1-mm2 (mm1 is OK) on RH 9.0.93 (Severn)

[Steven Cole]

I get this error when trying to boot 2.6.0-test1-mm2 using the new Red
Hat beta (Severn).  2.6.0-test2-mm2 runs successfully on a couple of
other test boxes of mine.

VFS: Cannot open root device "hda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)

Linux-2.6.0-test1-mm2 had this additional akpm patch applied:
http://marc.theaimsgroup.com/?l=linux-mm&m=105868155010855&w=2

Here is my /etc/lilo.conf.  All the other kernels boot and run fine.
I removed the devlabel stuff from virgin Severn (fstab and rc.sysinit).

The .config for -mm2 is the same as for -mm1, just run through 
make oldconfig. That -mm1 .config came from the working 2.6-bk .config,
also run through make oldconfig too.

 The last time I had this problem, I found that
CONFIG_IDEDISK_MULTI_MODE was off and my disk wouldn't
get recognized without that. But you say your other
kernels are working, so I am not sure this is the problem.

Thanks, but in this case, that's not it.

[steven@spc1 linux-2.6.0-test1-mm2]$ grep ^CONFIG_IDE .config
CONFIG_IDE=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_IDEPCI_SHARE_IRQ=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_IDEDMA_AUTO=y

I may try to build the kernel with another compiler. Severn has this
fairly new gcc:
[steven@spc1 etc]$ gcc --version
gcc (GCC) 3.3 20030715 (Red Hat Linux 3.3-14)

After reading a recent thread on lkml, I changed the "root=" thusly:

image=/boot/vmlinuz-2.6.0-test1-mm2
        label=2.6.0-test1mm2
        read-only
        append="devfs=nomount hdc=ide-scsi root=/dev/hda1"

to this
        append="devfs=nomount hdc=ide-scsi root=0301"

And now 2.6.0-test1-mm2 boots and runs.
