Am suspecting this commit or related: commit 9c8573ca6e35f327d53cb46aba017b95e05d8e08 Author: Bob Moore Date: Wed Nov 12 15:15:29 2008 +0800 ACPICA: Add a mechanism to escape infinite AML While() loops Add a loop counter to force exit from AML While loops if the count becomes too large. This can occur in poorly written AML when the hardware does not respond within a while loop and the loop does not implement a timeout. The maximum loop count is configurable. A new exception code is returned when a loop is broken, AE_AML_INFINITE_LOOP. Bob Moore, Alexey Starikovskiy. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown This is a Dell Latitude D820, and didn't seem to have any infinite AML loops to escape, at least none that I actually hit with previous kernels...
