(btw, If I use the= =20 standard ACPI from 2.4.20, ACPI works fine (if I uncomment a couple of line= s=20 which stated my BIOS as being on the blacklist) - except with this version = of=20 ACPI I don't have access to the toshiba module :(=20 I tried snooping around, but writing a 0xff to /proc/*_debug (don't remembe= r=20 the exact filename) produced too much output and I was unable to get back t= o=20 the console (geeezzz) C-M-Sys_Req-b was the only way to restart it :P I found a particular dmesg line interesting (I'll just post everything rela= ted=20 to ACPI): ACPI: Subsystem revision 20030109 PCI: PCI BIOS revision 2.10 entry at 0xfd4df, last bus=3D5 PCI: Using configuration type 1 tbxface-0098 [03] acpi_load_tables : ACPI Tables successfully acquired =2E........................................................................= =2E..........................
