Subject: PAT support (or lack of) for Pentium 3 CPU's
Date: Tue, 16 Jun 2009 08:09:04 -0700 [thread overview]
Message-ID: <20090616080904.CCA17C3A@resin11.mta.everyone.net> (raw)
It has come to my attention that PAT support has been disabled for P3 CPU's in kernel versions 2.6.30 and later due to a bug in the CPU.
I have attempted to get the NVIDIA proprietary drivers working with these kernel versions and 3 different Pentium 3 motherboards, all have failed. The drivers seem to require PAT support in order to work correctly, each board has in fact produced a different error when using only MTRR.
Can a kernel option be added to enable/disable PAT for P3 CPU's? Or is there any possible workaround for the bug?
I'd be interested to hear from Radeon users running a 2.6.30 or later kernel.
For anyone wondering why I still use such an old machine, I require ISA support.
Cheers,
Brad Allen
