Package: linux-image-3.2.0-4-amd64 Version: 3.2.60-1+deb7u3
I'm using an Intense PC 2 from Compulab. This is a 100% fanless server but ACPI complains about ACPI Errors and FAN1 failing transitions. The error occurs after some random time. $ tail -n 200 /var/log/messages |grep ACPI Aug 14 16:29:52 ipc kernel: [86779.761708] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.H_EC.ECMD] (Node ffff88040dc8b5b0), AE_AML_INFINITE_LOOP (20110623/psparse-536) Aug 14 16:29:52 ipc kernel: [86779.761715] ACPI Error: Method parse/execution failed [\_TZ_.FN01._ON_] (Node ffff88040dc90290), AE_AML_INFINITE_LOOP (20110623/psparse-536) Aug 14 16:29:52 ipc kernel: [86779.761721] ACPI: Device [FAN1] failed to transition to D0 Aug 14 16:29:52 ipc kernel: [86779.762789] ACPI: Device [FAN1] failed to transition to D0 Aug 14 16:29:52 ipc kernel: [86779.960606] ACPI: Device [FAN1] failed to transition to D0 Aug 14 16:29:53 ipc kernel: [86780.269908] ACPI: Device [FAN1] failed to transition to D3 Aug 14 16:29:54 ipc kernel: [86781.301032] ACPI: Device [FAN1] failed to transition to D3 Aug 14 16:30:00 ipc kernel: [86787.281157] ACPI: Device [FAN1] failed to transition to D3 Aug 14 16:30:00 ipc kernel: [86787.797083] ACPI: Device [FAN1] failed to transition to D3 This is an extract of all ACPI events during boot : [ 0.615020] ACPI: Power Resource [FN00] (off) [ 0.615086] ACPI: Power Resource [FN01] (off) [ 0.615147] ACPI: Power Resource [FN02] (off) [ 0.615205] ACPI: Power Resource [FN03] (off) [ 0.615264] ACPI: Power Resource [FN04] (off) .
