I'm helping a friend install his jazz (1GB) disk in Arch. The installation of Arch was a breeze but the jazz drive has turned to be a pain.
The system has an Adaptec 2940U2/U2W and it is properly detected and a AIC7xxx driver is loaded for it. The following related modules are also loaded: sd_mod, sr_mod and st.
But ... there has to be one or I would not be posting ... The system will go into a kernel panic after detecting it.
I can see (on the screen) that it was detected and it loads the adapter and drivers and then it dies.
The system has just two partitions the swap and the /. I think that after loading the jazz drive it messes up the partition order and the system cannot longer see the boot section.
Any help, ideas, guidance ?
Thanks in advance guys!

Could you please post the output of what you see on the screen?
(just relevant lines)

Well... those are in essence the most critical lines. I've typed the info because there is not "copying and pasting" after the system gives a kernel panic ;-)
The drive is recognized (or at list it flashes for half a second on the screen) as sda4 which to me is somehow wrong since the natural order should be sda3 but it may be "acounting" for settings for the USB drive or something.

sda = first hard drive
sdb = second hard drive
if jazz drive is sda then your original hard drive got moved to sdb# go into /etc/fstab & change the the "/" dev
"/dev/sdb1 swap swap defaults 0 0
/dev/sdb2 / ext3 defaults 0 1"
this can be accomplished from booting the install cd & mounting your drive then edit

But the point here is more to the fact that by adding the scsi drive I should not have to re-configure my logical boot.
Sure I could go and change all the settings in grub but there should be a way to "tell" the jazz drive to go to the next available drive instead of setting itself as sda1 since sda1 is already defined.

yes you could write a udev rule to change the naming scheme but i dont know if or how that would effect booting
i am unfamiliar with jazz drives is this ide scsi sata usb ?
your primary drive is it ide sata scsi ?
you may get away with editing /etc/mkinitcpio.conf

The Jazz "thing" is scsi II or III, I think. It runs off an an SCSI adapter. I think that's the reason it takes precedence over the HDD which is EIDE but Arch presents it as a SCSI (/dev/sda) to the kernel.
I noticed that if I unplug the drive the adapter by itself is recognized but there are not problems it is only when the SCSI drive is connected at boot that the problem appears.
Thank you for the ideas I'll try to read a bit about using udev to get it going. I've added scsi to /etc/mkinitcpio.conf and that seems to work fine.

remove scsi from hooks in mkinitcpio.conf & any/all modules you may have in there associated with scsi
that way the 1st drive being recognized is hdd=eide which will be given sda anydrives recognized after that will get sdb,sdc , etc...
thats what i believe you want to happen

Never mind my friend just told me that this is too complicated and it is better to use his USB pen drive to do the work.
That ... works for me

I'll be happy to give it a try but my friend took the machine with him.
I may be able to get it back on Friday and if he is willing to try again I'll let you know if your idea works.
Thanks for all the help!!
Let's see if he want to keep going.
