VFS: Unable to mount root fs on 08:06 - 2.4.19-pre6

This machine worked with 2.4.19-pre5. 2.4.19-pre6 has worked on another machine (entirely different hardware).

Boot message:
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
VFS: Cannot open root device "806" or 08:06 Please append a correct "root=" boot option

Kernel panic: VFS: Unable to mount root fs on 08:06

Lilo has this entry for all kernels:
root=/dev/sda6

2.4.19-pre6-aa1 gives same error.

Did "make oldconfig" from previously working .config. This is the difference between the two configs.
