It took me a month, but I finally found time to build a 2.6.16 kernel

his reply:
######
People report crash when the kernel is configured with a 4ko stack
CONFIG_4KSTACKS
you should never set this, the jpeg decoder inside the spca5xx module
need a
8ko stack.
People report crash with FC5 and gcc 4.1, setting in the Makefile this
option
for CFLAGS fix the problem
-fno-unit-at-a-time
I am using OpenSuse set with 2.6.16 and gcc 4.1 without any problem

I also tested his -fno-unit-at-a-time workaround, and it made no
difference for me. His requirement of having an 8K stack seems
ridiculous to me. This is a webcam driver, it shouldn't need an 8k
stack, especially since no others in the kernel have that requirement.

Kernel.org kernels don't even have a CONFIG_4KSTACKS option any more.
Looks like this driver needs some work.
