When boot fails it is not possible to read the attempt to load the
driver however root FS fails to mount:

request_module[block-major-8]: Root fs not mounted
VFS: Cannot open root device "sda2" or 08:02
Please append correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:02
                                                                     
          



Version-Release number of selected component (if applicable):
LSI megaraid2 v2.10.1.1

How reproducible:
Always

Steps to Reproduce:
1. Set Grub to boot 2.4.9-e.40smp
2. Reboot machine 
3. Root FS fails to mount
    

Actual Results:  Machine fails to boot.

Expected Results:  See text above - MegaRaid driver should have loaded
normally and detected sda.

Comment 3 Tom Coughlan 2004-05-17 16:51:21 UTC

I am reopenning this bug.  I do not think it is a duplicate of 75090.

Comment 4 Tom Coughlan 2004-05-17 16:59:14 UTC

Please check your /etc/modules.conf file.  If there is an entry for
the megaraid_2002 driver, then remove this line and replace it with
"megaraid2".  Then try the upgrade again.  The megaraid_2002 driver
was removed in U4.

Comment 5 Mark Henson 2004-05-19 21:45:58 UTC

Current /etc/modules.conf

alias parport_lowlevel parport_pc
alias scsi_hostadapter megaraid_2002
alias eth0 e1000
alias scsi_hostadapter1 aic7xxx
alias scsi_hostadapter2 aic7xxx
alias scsi_hostadapter3 aic7xxx
alias usb-controller usb-uhci

Will test changing megaraid_2002 to megaraid2 - however this must be
done out of hours so it may take a couple of days to test.

Comment 6 Mark Henson 2004-06-02 16:48:46 UTC

Ok, have tested change from megaraid_2002 to megaraid2 and we have the
same result.  when booting 2.4.9-e.38smp with this driver (megaraid2)
everything works perfectly.  If neccesary I can setup to capture the
boot messages by serial.  

The behaviour of megaraid2 is unchanged from megaraid_2002

Comment 7 Jason Baron 2004-06-02 17:25:49 UTC

after editing /etc/modules.conf, did you re-install the  kernel rpm?
The 'initrd' needs to pick up the change in /etc/modules.conf, and a
re-install of the kernel rpm will pick that up.

Comment 9 Mark Henson 2004-06-25 21:46:16 UTC

Thanks.  Changes noted here have worked with RH latest kernel.
