Unable to mount the root fs on stable/8 r264339, GENERIC kernel,

Hi,

I have a couple of uncritical systems running stable/8 r258344.
Hardware is Dell OptiPlex GX260, BIOS A09, which is the latest rev.

The r264339 GENERIC kernel are unable to mount the root fs from the =

hard drive using MBR, FreeBSD slice, and UFS volume labels.

r258344 obviously can.

I even tried regular device names like /dev/ad0s1a in /etc/fstab, and =

at the mountroot> prompt, i.e. ufs:/dev/ad0s1a. The kernel still =

cannot mount the root fs.

The new kernel (r264339) does recognize the ad0 harddrive, and ad0 is =

listed as one of the GEOM managed disk devices; acd0 being the other =

one.

Do I need to load additional geom modules, or is it a genuine bug?

I have recreated the same conditions on a spare GX260, yes, I have =

plenty of them.

In addition there was some problems with the USB subsystem, so I =

disabled USB in the BIOS for now. USB is not essential for any of my =

systems.

Maybe it's time to leave stable/8 and enter stable/10 or stable/9.
I'll try to compile stable/9 on the spare system, and see how it =

fares.

Any thoughts regarding the problem mounting the root fs?
