::You have the VIA 82c686b southbridge chip which is known to cause severe
::data corruption problems if the BIOS does not setup the northbidge
::chip correctly. Please check with your board vendor if they have a
::new updated BIOS that fixes this problem. This is not an ATA specific
::problem, but a problem with the PCI subsystem in general on these
::chips that manifests it self on high PCI load (which the ATA subsytem
::is quite capable of delivering)...
::
::A fix for this is present in -current, and if I get permission from
::the RE, it will go into 4.5 also, but a BIOS fix is by far the right
::way to fix this problem.

: Soren, if you post a patch for 4.x I will be happy to follow-up
: with Brady. I've been working with Brady for several days now trying
: to track down corruption in the vm_page array. I *really* want to know
: if a VIA chipset patch solves his problem, because it would
: also explain about a dozen similar bug reports over the last 6 months.
: (Which would also be good backing to get it into 4.5).
Sorry, I meant I'd follow up with Matthew Gilbert. Also, I've
been trying to track down a crash in nfs_node that Nils Holland
has been having - he appears to have the same chipset and could
have the same problem, and he can reproduce the panic very consistently
within a few hours.
Brady has an older chipset. Are there any known problems with this
chipset?
