Since I'm using 9.0, I've had weird problems with a couple of programs.
One of them is a software vcr, http://www.stack.nl/~brama/vcr/, slightly modified to work with the current avifile in plf.
As soon as I start it I have an instant kernel lock up.
I made various experiments, and I finally settled to downgrading the kernel to 2.4.18-8.1mdk.
Then I heard of a guy that was having problems with video capture under mandrake 9.0, and solved them by recompiling a vanilla kernel with athlon optimizations.
So, unwilling to compile the kernel, I grabbed the athlon optimized kernel from sgi (which is plain 2.4.19+xfs patches), installed it, tried vcr and...instant crash.
So I downloaded the kernel source (still plain 2.4.19) and xfs patches (1.2pre3), compiled it, installed it, tried it and...instant crash.
Went back to 2.4.18-8.1mdk.
Then I thought that the common trait among the failing kernels was that all were compiled with gcc3.2 (yes, the rpm from sgi too).
So I recompiled the kernel with egcs-2.91.66, installed it, tried vcr and...it worked, no instant lock up.
I tried to rebuild the mandrake kernel source rpm with the same compiler but I couldn't. I compiled it with gcc2.96 (after dropping an atm driver that didn't compile, and I don't need it anyway), installed it, tried it and ...it worked.
My hardware isn't so exotic, and this program isn't doing anything really weird (capture video and audio and compress it to divx), so I don't think I'm the only one having problems.
As I said, I don't follow kernel development, but I can say that a kernels compiled with gcc3.2 fails for me, while the same kernels compiled with egcs 2.911.66 or gcc 2.96 work (or at least they don't crash immediately).
Bye
