Ok,
when compiling the BTTV driver I get this error:
iwithprefix include -DKBUILD_BASENAME=bttv_driver -c -o bttv-driver.o
bttv-driver.c
bttv-driver.c: In function `do_bttv_mmap':

I enabled modules support in my kernel source and did a make dep to get
over the fact that the kernel source I had did have loadable modules
support. This then allowed me to at least get a few seconds into the
driver compile to get this message. Before I start to pick the code
apart... has anyone seen this or has a fix?
regards
Pete

Increase the value of BTTV_MAX (defined in bttvp.h) and recompile
the driver.
