Hi!
(Please CC me your answers as I am not subscribed.)
I have a problem with 2.6.14.3 kernel (but this probably isn't too
version-specific). I have a kernel which succesfully boots on totally
random basis (cca 70% is success). My root partition resides on a SATA
disc connected to a controller on Intel 6300ESB ICH southbridge (mb
Intel se7320vp2). There is a reiserfs 3 filesystem on my root partition.
Without any changes to configuration (os or bios or whatever) I
sometimes get:
VFS: Cannot open root device "801" or unknown block(8,1)
Could this be some timeout issue, or indication of crappy hw? I've tried
this about 10 times (immediately ctrl+alt+del on successfull boot or
reset button on aforementioned panic) and I saw no regularities in this
misbehaviour.
I sincerely appreciate any advice anyone can give.

Hello, 0602. :-)
Can you please post dmesg of a successful booting? That will tell us
which SATA controller/disks you are using. Also, the boot log of a
failed boot will be very helpful - the best way to get this is via
serial console. If you don't have access to serial console, taking note
/ picture of the part where SATA detection fails will do too.
Also, when the machine boots successfully, does it work without
generating disk related kernel logs? Just perform any IO-heavy
operations - cp'ing directories which contain large files,
tar/untarring... - and see if the kernel complains about anyting.
