I think you don't have to say this without any proof. There is some
drivers which have problems to support fedora mainly due to kernel
versioning (see for example ).
I don't say this is the problem with spca5xx driver i only say it is not
so simple as you said ...
No, that's not the issue I'm experiencing.  The spca5xx module builds
just fine on my FC5 system.  The problem is that as soon as its used,
I encounter an immediate kernel panic.  I have proof that the
developer has taken zero interest in attempting to debug the problem.
Initially he was claiming that FC kernels are just buggy, so I tried a
vanillla kernel, and that, too, exhibited the same problem
(kernel panic).

His response was that it had to be a gcc-4.x issue.  This turned out
to be partly true, as rebuilding the kernel with gcc-3.x did eliminate
the problem.  However seeing as how every other in kernel module isn't
having this problem in a kernel built with gcc-4.x, i'm more inclined
to believe that spca5xx is broken with gcc-4.x, not that gcc-4.x is
broken with spca5xx.

At any rate, I pushed back on the developer noting that at some point
he needs to fix this problem or work with the gcc folks, as he can't
just rely on gcc-3.x forever.   His response was that it must be a FC
problem, since he had upgraded to SuSE-10 which had gcc-4.x and he
wasn't having the problem there, and its likely a lack of 8k stacks in
the FC x86 kernels.  That is complete nonsense since all
x86 kernels build with 4k stacks, and nothing greater is even possible
without alot of hacking.  I pointed that out to the developer, and he
never replied.  I sent another email asking him for assistance, and
there was no reply.

The bottom line is that this guy clearly has no clue what is wrong,
and as long as it "works for him" he has no interest in investigating.
