Please queue
84113717 (x86/PCI: use host bridge _CRS info on MSI MS-7253)
a97f4f5e (x86/PCI: do not tie MSI MS-7253 use_crs quirk to BIOS
version)
for maintained stable trees 2.6.34.y and newer.
Those two patches address a regression that bisects to
v2.6.34-rc1~218^2~26 (x86/pci: AMD one chain system to use pci read
out res, 2010-02-10) and on the affected machines (Microstar MSI
MS-7253) results in misconfiguration and instability --- some example
symptoms were audio being silenced and crashes at boot time. They
work by automatically enabling the pci=use_crs parameter so the kernel
can pay attention to information in ACPI tables that can save it from
trouble.
The patch was applied to mainline during the 3.3 merge window.
https://bugzilla.kernel.org/show_bug.cgi?id=42619 has details.
Thanks to Svante Signell and Carlos Luna for reporting it and Bjorn
Helgas and Paul Menzel for tracking it down.
Jonathan
