I've compared dmesgs and these lines are missing when I boot the bad
kernel:
k8temp0: <AMD K8 Thermal Sensors> on hostb3
acd0: DVDR <ASUS DRW-2014L1T/1.00> at ata2-master SATA150
ad6: 143089MB <WDC WD1500ADFD-00NLR5 21.07QR5> at ata3-master SATA150
The drives aren't found, so not root filesystem.
It turns out that the problem is caused by this commit:
SVN rev 181987 on 2008-08-22 02:14:23Z by jhb
Extend the support for PCI-e memory mapped configuration space access:
Reverting this fixed the problem. The drives are found again (and
so are the thermal sensors).
The machine is based on an nForce 570 SLI MCP chipset (Asus M2N-SLI
Deluxe). Here's the dmesg, minus the witness chatter on root mount:
