Hi Thinkpad users, I have tried the kernel 2.4.22-pre5 with the newest acpi patch. Unfortunately it does not work for the IBM Thinkpad A31. The last known working kernel was 2.4.21-rc1 + acpi patch, where at least the battery state worked correctly. Does anybody know why the acpi does not work properly? Are there any other IBM Thinkpad users out there having the same problem? Greetings, Dominik Bartenstein p.s. I am running a pretty recent version of the IBM Thinkpad BIOS.
