sda becomes sdb

i'm trying to install gentoo (vmware, the only virtual scsi disk - LSI Logic).

after recompiling the kernel and rebooting - sda becomes sdb and of cause, i'm getting kernel panic.
any ideas about that?

I noticed that the labeling of the disks depends on whether the corresponding module is compiled as a module or included in the kernel. I don't know why, but it happens.
So you can recompile the kernel changing the way you load the specific module that you need for this disk: if now you have it as module, turn it into build in, or viceversa.
Hope it helps.

Regards.

depending on how the machine (or virtual machine) enumerates PCI (virtual) devices, the controllers that get probed first will end up with the first device letters. If you only have one driver to probe, then it will get the first one since it's the only one...

You could clean this problem up by referring to disks by UUID. But that's beyond me at the moment, I'm old fashioned...

i had the same problem because i had an external usb dvd drive connected at boot and it took the /dev/sda# i.d. when i unplugged the external device and rebooted all was well. might be your problem... hope it's that simple.

maybe try looking for an option "boot off board chipset first"
that may affect this
