Hello everyone, I've got a problem with one of my home debian nodes and I'm lead to believe it is to do with the acpi system. When installing 2.6.26 (debian vanilla) the system randomly locks up with the message: BUG: soft lockup detected on CPU#0! 61s While kacpid consumes 100% cpu according to top. With this being an older kernel I took it upon myself to build 2.6.31 to see if there was any change. The system does not lock up any more, but kacpid still consumes close to 100% cpu and I'm getting this in my dmesg: [45699.978868] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.SMBR] (Node f7812c48), AE_AML_INFINITE_LOOP [45699.978905] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.INIT] (Node f7812c30), AE_AML_INFINITE_LOOP [45699.978936] ACPI Error (psparse-0537): Method parse/execution failed [\_GPE._L00] (Node f78101b0), AE_AML_INFINITE_LOOP [45699.978970] ACPI Exception: AE_AML_INFINITE_LOOP, while evaluating GPE method [_L00] 20090521 evgpe-568 (constantly repeating). The system is an Intel Atom Little-Falls mini itx board with 1gb ram which I've checked with memtest86. lspci output: 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 01) 00:1c.2 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 3 (rev 01) 00:1c.3 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 4 (rev 01) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
