Bug Description

Binary package hint: linux-image-2.6.28-11-generic

On updating the system from Intrepid to Jaunty, on the first reboot, the kernel crashes immediately on loading, with:

BUG: Int 14: CR2 ffffb0f0

And a dump of registers and the stack. I can transcribe by hand the numbers if someone's sufficiently interested. NB: The words "Panic" or "Oops" don't occur.

The residual Intrepid kernel still boots me into the otherwise apparently functional Jaunty system, but I'd guess this isn't a long-term solution.

Working: linux-image-2.6.27-11-generic version 2.6.27-11.31
Failing: linux-image-2.6.28-11-generic version 2.6.28-11.42

CPU shows in /proc/cpuinfo as a "Via Samuel 2", on board an EPIA-5000 mini-itx board. System has run Hardy for some time, and went through a successful upgrade to Intrepid earlier this evening, before being upgraded again to Jaunty.

I know it's old. Was support for these chips/systems deliberately dropped, or should I make sure something's set in BIOS or kernel params, or does someone want me to type up the crash dump. :-)
