I always had trouble with rebooting, and shutting down, it just didn't happen. With this kernel the machine does shut down properly and reboots properly, so that is fixed now. Better not touch it :p I tried fixing my DSDT by disassembling it, fixing the warnings that turned up with iasl, and putting it back in the kernel with the appropriate patches, but it didn't change a thing, so it seems. Ofcourse I don't know if I fixed it The Right Way(TM). Okay, next I tried 'sleep modes'. Because I want to be able to suspend my laptop. cat /proc/acpi/sleep displays: | S0 S3 S4 S4Bios S5 S0 = Default operation, so that works :p S3 = echo: write error: no such device S4 = Laptop suspends, wakes up, but after waking up, it hangs S4Bios = See S4, exactly the same behaviour S5 = Kernel Oops: | kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000000 | kernel: printing eip: | kernel: c01130cb | kernel: *pde = 00000000 | kernel: Oops: 0002 | kernel: CPU: 0 | kernel: EIP: 0010:[acpi_restore_pmd+11/32] Not tainted | kernel: EFLAGS: 00013002 | kernel: eax: 00000000 ebx: 00000001 ecx: 00000005 edx: 00000000 | kernel: esi: 00000005 edi: 00000005 ebp: c129c7e4 esp: c8dd3f28 | kernel: ds: 0018 es: 0018 ss: 0018 | kernel: Process zsh (pid: 511, stackpage=c8dd3000) | kernel: Stack: c01ddab7 00000001 c01ddc07 00000005 00000005 00000002 c8dd3f50 c8dd3f60 | kernel: c01de49c 00000005 02000000 c02e3acd c02e39bc c9149104 00000a35 00000000 | kernel: 00000000 c9149104 00000000 c8d52964 ffffffea 00000002 c0156a70 c8d52964 | kernel: Call Trace: [__constant_c_and_count_memset+106/115] [acpi_suspend+32/155] [acpi_system_write_sleep+168/251] [proc_file_write+64/80] [sys_write+163/320] | kernel: [system_call+51/56] | kernel: | kernel: Code: 89 02 0f 20 d8 0f 22 d8 a1 84 d9 36 c0 31 d2 e9 a1 f1 01 00 I hope this information helps!
