Distribution: Debian Sarge Hardware Environment: Compaq Evo N600c Problem Description: Following Len Brown's answer to my initial email http://lkml.org/lkml/2005/1/24/334 There's no more ACPI working on 2.6.11-rc2-mm1. Reverting the bk-acpi.patch makes it work.

Looks like a problem with the global lock was introduced in 20050114. Will fix and release immediately.
please test the 2.6.10 patch here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.10/acpi-20050125-2.6.10.diff.gz or the 2.6.11 patch here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.11/acpi-20050125-2.6.11-rc2.diff.gz
Works on top of 2.6.11-rc2 (and also on top of 2.6.11-rc2-mm1 without its bk-acpi.patch). At least fans, battery and thermal_zone are back. I still have these on dmesg but I think it's another problem: Jan 27 01:11:12 localhost kernel: evgpeblk-0275 [08] ev_save_method_info : Unknown GPE method type: C13E (name not of form _Lxx or _Exx) Jan 27 01:11:12 localhost kernel: evgpeblk-0275 [08] ev_save_method_info : Unknown GPE method type: C18F (name not of form _Lxx or _Exx) Jan 27 01:11:12 localhost kernel: evgpeblk-0275 [08] ev_save_method_info : Unknown GPE method type: C1DC (name not of form _Lxx or _Exx) Jan 27 01:11:12 localhost kernel: evgpeblk-0979 [06] ev_create_gpe_block : GPE 00 to 0F [_GPE] 2 regs on int 0x9 Jan 27 01:11:12 localhost kernel: evgpeblk-0987 [06] ev_create_gpe_block : Found 3 Wake, Enabled 1 Runtime GPEs in this block Jan 27 01:11:12 localhost kernel: evgpeblk-0275 [08] ev_save_method_info : Unknown GPE method type: C13E (name not of form _Lxx or _Exx) Jan 27 01:11:12 localhost kernel: evgpeblk-0275 [08] ev_save_method_info : Unknown GPE method type: C18F (name not of form _Lxx or _Exx) Jan 27 01:11:12 localhost kernel: evgpeblk-0275 [08] ev_save_method_info : Unknown GPE method type: C1DC (name not of form _Lxx or _Exx) Jan 27 01:11:12 localhost kernel: evgpeblk-0979 [06] ev_create_gpe_block : GPE 10 to 1F [_GPE] 2 regs on int 0x9 Jan 27 01:11:12 localhost kernel: evgpeblk-0987 [06] ev_create_gpe_block : Found 2 Wake, Enabled 5 Runtime GPEs in this block Thanks a lot.
