ICH5 > 2.6.11 kernel panic

[tlc]

P4P800-E Delux / 3.0E / 2GB ram / 80GB sata ( ICH5 )
FC3 upgraded to FC4
2.6.11.12 #5 SMP Thu Oct 20 17:18:06 EDT 2005 i686 i686 i386 GNU/Linux

SATA set to compatibility mode, secondary PATA + SATA.

SATA boot drive, CD/DVDRW on PATA ( secondary )

The 2.6.11 kernel works fine, it sees my sata drive as /dev/sda and my
cds as /dev/hdc and /dev/hdd

When I try to upgrade past 2.6.11, I get a kernel panic on boot.

Kernel panic - not syncing: VFS : Unable to mount root fs on
unknown-block(0,0)

I have not paid much attention to the problem ( lack of time ) but I
would like to get this resolved as hald and udev act funny under 2.6.11,
so I compile a 2.6.14 kernel and I get the same error.

I have also tried the default FC4 kernels and past 2.6.11 I get the same
problem, and I have it on more then one machine. I have it on base
installs after I do an upgrade.

So I am assuming a driver was changed, or split, or something ..

I can't paste the boot up log because it scrolls by too fast and the
file system does not mount so it can not save it any where.

I suspect it is not finding/using the sata drive and hence the error.

Anyone have any clues?
