    [solved] kernel update 3.x to 3.6.2 stopped system boot from ide drive


    I updated my system today which included a kernel upgrade from
    Code:
    Linux Desktop-PC 3.5.6-1-ARCH #1 SMP PREEMPT Sun Oct 7 19:33:50 CEST 2012 i686 GNU/Linu
    to
    Code:
    Linux Desktop-PC 3.6.2-1-ARCH #1 SMP PREEMPT Sat Oct 13 07:19:40 CEST 2012 i686 GNU/Linux
    After a reboot I got error messages about being unable to read the hard drive ... after some searching I came across this thread indicating a problem with pata_acpi.

    I checked when dropped to a recovery shell the output of lspci -vnn and found that relevant output for my ide controller had changed from
    Code:
    00:04.0 IDE interface [0101]: ULi Electronics Inc. M5229 IDE [10b9:5229] (rev c4) (prog-if fa)
            Subsystem: ASUSTeK Computer Inc. A7A266 Motherboard IDE [1043:8053]
            Flags: bus master, medium devsel, latency 32, IRQ 255
            [virtual] Memory at 000001f0 (32-bit, non-prefetchable) [size=8]
            [virtual] Memory at 000003f0 (type 3, non-prefetchable)
            [virtual] Memory at 00000170 (32-bit, non-prefetchable) [size=8]
            [virtual] Memory at 00000370 (type 3, non-prefetchable)
            I/O ports at d400 [size=16]
            Capabilities: <access denied>
            Kernel driver in use: pata_ali
    to using kernel driver pata_acpi

    Adding modprobe.blacklist=pata_acpi to the kernel boot parameters fixes the issue for me

    thought I'd share my solution incase it helps others with similar issues ...
