Hi,
i'm running GNU/Gentoo Linux with a custom compiled kernel and i've just
migrated from a 2.6 kernel to a 3.5.
As my HD's are on raid 0 mode i use a custom initrd file in order to be
able to boot. While kernel 2.6 is able to boot without problems the new 3.5
compiled kernel fails to boot complaining about "no block devices found".
After taking a look at initrd.cpio contained scripts i can see the failure
message is given by mdadm tool.
Does anyone has a clue about that? Thansk in advanced. :)

Add "set -x" to the top of your custom init script to see what's going on.

Paul,
I had a similar issue with a new system. There it was caused by mdadm trying to start the raid devices before all the drives were identified.
Try disabling "Asynchronous SCSI scanning" in the kernel config. (CONFIG_SCSI_SCAN_ASYNC)
Or add "scsi_mod.scan=sync" to the kernel commandline to see if it's the same cause.

Hi,
thanks a lot for both answers.
I've just checked my kernel config and CONFIG_SCSI_SCAN_ASYNC is not setted
so gonna take a look at it all with "set -x".
Thanks :)

There is a bug with certain versions of mdadm failing to assemble
arrays, maybe you using one of the affected versions.

Thx a lot Paul,
this morning i noticed there was some kind of issue on my old initrd which
works fine for 2.6 kernels, so created a new initrd which works fine and
let me to boot into GNU/Gentoo Linux with same 3.5 bzImage.
Gonna check if the issue came from mdadm, thx :)
