But I get /proc/ac_adapter /proc/battery etc. which should be in /proc/acpi if I'm correct. Nevertheless, only newer BIOS version cause a panic (with a complete lockup), the version I use currently gives the following dmesgs: ACPI: RSDP (v002 IBM ) @ 0x000f6d20 ACPI: XSDT (v001 IBM TP-1P 00000.04224) @ 0x1ff6b501 ACPI: FADT (v003 IBM TP-1P 00000.04224) @ 0x1ff6b600 ACPI: SSDT (v001 IBM TP-1P 00000.04224) @ 0x1ff6b7b4 ACPI: ECDT (v001 IBM TP-1P 00000.04224) @ 0x1ff74e89 ACPI: TCPA (v001 IBM TP-1P 00000.04224) @ 0x1ff74eda ACPI: BOOT (v001 IBM TP-1P 00000.04224) @ 0x1ff74fd8 ACPI: DSDT (v001 IBM TP-1P 00000.04224) @ 0x00000000 ACPI: BIOS passes blacklist ACPI: MADT not present Building zonelist for node : 0 [...] ACPI: Subsystem revision 20030619 tbxface-0117 [03] acpi_load_tables : ACPI Tables successfully acquired Parsing all Control Methods:................................................................................................................................................................................................................................................................................................................................................
