Previously I would occasionally get failed EcRead's do to timeout reading the battery and thermal status after the machine had been up for a while, but battery status still worked. Setting the event_driven tunable made no difference. With this patch, the EC is very, very broke. I now get spammed during bootup with a flood of failures from EcCommand: EC Waited max 16 cycles, event occurred acpi_ec0: EcCommand: no response to 80, disabling burst mode ACPI-0432: *** Error: Handler for [EmbeddedControl] returned AE_ERROR ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.PX41.SECN.BEXT] ( Node 0xc3342260), AE_ERROR ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.PX41.SECN.MAST._S TA] (Node 0xc3342320), AE_ERROR acpi_ec0: EcCommand: no response to 80 ACPI-0432: *** Error: Handler for [EmbeddedControl] returned AE_ERROR ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.PX41.SECN.BEXT] ( Node 0xc3342260), AE_ERROR ACPI-1287: *** Error: Method execution failed [\\_SB_.PCI0.PX41.SECN.MAST._S TA] (Node 0xc3342320), AE_ERROR etc. Also, my mouse now is acting up and the keyboard now drops characters. Battery status no longer works and neither does thermal status. Messing with the AC adapter does still work but all the GPE's fail. This has seriously hosed my machine. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/
