>Description:
On my Acer 5024WLMi laptop, I get tons of the following ACPI errors:

kernel: ACPI-1304: *** Error: Method execution failed [\_TZ_.TZSV._TMP] (Node 0xc4e84820), AE_NO_HARDWARE_RESPONSE
ACPI-0501: *** Error: Handler for [EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE

These two errors happens in the same minute and every few minutes:
May 31 00:07:52 Scarface kernel: ACPI-0501: *** Error: Handler for [EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE
May 31 00:07:52 Scarface kernel: ACPI-1304: *** Error: Method execution failed [\_TZ_.TZSV._TMP] (Node 0xc4e84820), AE_NO_HARDWARE_RESPONSE
May 31 00:08:12 Scarface kernel: ACPI-0501: *** Error: Handler for [EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE
May 31 00:08:12 Scarface kernel: ACPI-1304: *** Error: Method execution failed [\_TZ_.TZS0._TMP] (Node 0xc4e84a40), AE_NO_HARDWARE_RESPONSE
May 31 00:08:22 Scarface kernel: ACPI-0501: *** Error: Handler for [EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE
May 31 00:08:22 Scarface kernel: ACPI-1304: *** Error: Method execution failed [\_TZ_.TZS1._TMP] (Node 0xc4e84940), AE_NO_HARDWARE_RESPONSE
>How-To-Repeat:
Just install FreeBSD 6.1 i386 on a Acer 5024WLMi laptop (or more probably, on any Acer 3020 / 5020 series laptop)
