This bug does not affect 64-bit kernels and if fixed by mainline commit 6a92b11169a6. == Fix == 6a92b11169a6 ("x86/EISA: Don't probe EISA bus for Xen PV guests") == Regression Potential == Low. This commit only affects x86 kernels. This commit has also been cc'd to upstream stable, so it has had additional upstream review. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug.
