Re: Unable to boot after upgrade to 7.0 or 7.1 STABLE

Hi All,

I have run into a problem that seem rather puzzling. I have upgraded an
installation of FreeBSD from 7.0-RELEASE to 7.0-STABLE and 7.1-STABLE, but i
fail to boot with either one of the STABLE upgrades. I end up at this point:


Trying to mount root from ufs:/dev/ad0s1a
Manual root filesystem specification:
<fstype>:<device> Mount <device> using filesystem <fstype>
eg. ufs:da0s1a
? List valid disk boot devices
<empty line> Abort manual input

When i type ?, i get nothing. When i try to load all possible drives, from
ad0s1a to ad9s1a, i get nothing. When i boot kernel.old, i see this:

atapci0: <Intel ICH7 SATA300 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xfa00-0xfa0f mem 0xfdffe000-0xfdffe3ff
at device 31.2 on pci0
...
ad0: 152627MB <WDC WD1600AAJS-60PSA0 21.12M21> at ata0-master SATA150

It seems that FreeBSD recognises this drive as a SATA300 but later on refers
to it as SATA150. Could this be the problem.

Have you checked the jumper settings on the drive? There may be a jumper forcing SATA150 mode on the drive. I'd reset everything to factory defaults if possible.

You might be able to use the ata driver from 7.0-R in -stable to boot your system. If that works, try searching for the commit that breaks your controller.
