across system suspends on the Intel 82371AB PCI-ISA bridge. On a Sony Vaio C1XD that I have, these registers are not set correctly after an ACPI resume. The result is that after resuming, a shared IRQ is left in edge-triggered mode so the interrupt can later become jammed in a state where the line remains asserted, but the handler is never called.
