[2.6.9-rc2-bk] Network-related panic on boot

[Bob Gill]

Hi.  I recently built 2.6.9-rc2-bk3.  It throws a panic on boot. 
2.6.9-rc2-bk2 boots OK.
The error message I get (copied by hand) is:
Enabling local filesystem quotas:                          [ OK ]

...and that's where everything stops.  If (you really want) I can send
the jpegs the digital camera made of the error.  I have a Soyo MB, with
a SiS chipset, the SiS 900 is the integrated 10/100 ethernet controller,
which lspci (from 2.6.9-rc2-bk2) shows as:
