(Note from Sarah: That's fixed by Andiry's patch before this, by synchronizing the irqs rather than freeing them on suspend.) Do not run xhci_cleanup_msix with irq disabled. This patch should be queued for the 2.6.37 stable tree. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@kernel.org |
