Prevent PCI config reads of Symbios controller that produce parity errors
A discussion of this problem can be found here:
The quick summary is that some tools perform PCI config reads to addresses
that are really meant to be internal to the Symbios controller.
My system has a Tekram DC-390U2W (SYM53C895) that gives a scsi parity
error coincident with haldaemon starting. If I prevent haldaemon from starting,
the parity error does not occur. The kernel is 2.6.9-34.EL from CentOS.
The attachment I submitted fixes the problem for me.
How does this patch look to you David?
Patch looks fine to me.
