Compiler bug causes detection loop in matroxfb_probe to fail
Last modified: 2007-11-30 17:11:32 EST
Description of problem:
matroxfb fails to detect GXT135P (PCI Matrox G450).
Version-Release number of selected component (if applicable):
Try to load the matroxfb module on a PowerPC system with a GXT135P card installed.
Steps to Reproduce:
I have submitted this bug against gcc4 because I have been told by various
people that the root problem is a compiler issue in GCC 4.1.0 and GCC 4.0.x. I
inserted some debug messages in the detection loop in matroxfb_probe, and I was
able to convince myself that this is the case.
As far as I know, this GCC bug *only* affects PowerPC.
Can you give a GCC PR#, or some more details of precisely where the
Which means it is fixed in rawhide GCC and will show up in FC5 updates testing
within a week.
