2.4.22-1.2179.nptl panic; mixing up SATA and /dev/hda
Last modified: 2007-11-30 17:10:40 EST
Description of problem:
I upgraded FC1 to 2.4.22-1.2179.nptl and the kernle panics claiming
there is no /lib/modules/2.4.22-1.2179.nptl/modules.dep
(but it exists)
As I can see my SATA disk containing FC2-test2 has been discovered as
SCSI /dev/sda (not as /dev/hde as earlier) and it seems the loader
tried to use the root filesystem of FC2 instead of FC1, which I have
on an Par-ATA disk (hda).
After disconnectinmg the SATA-cable to the disk the system boots
correctly (root on /dev/hda2).
I.e I have: FC1 on /dev/hda, FC2 on SATA (/dev/hde or now /dev/sda)
Each disk has own MBR/Grup and does not know anything about the other
disk - I change boot device from BIOS-setup.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. SATA-disk with FC2
2. ATA-disk with FC1/*.2179
after further investigation the reason I got the the panic could be
that I (or rather xcdroast) activaded hdc=ide-scsi for my CDROM-RW
device, and loads scsi_mod.
I tried to force loader to use root=/dev/hda2, but it still gets
confused claiming dupplicate root=LABEL=/ .
It's not a bug. I has same labels on both disks which confused the system.
The error occured when I installed ide-scsi for my CD-burner and the
SATA disk become visible.
