    SubjectSystem lockup with 2.6.38-rc4+
    Date
    Hi,

    I'm not subscribed, so please cc me on any reply.

    I've just had a complete system lock up with a kernel that I pulled, built and
    installed yesterday morning. IT was locked hard and I had to power off and on
    to get it back.

    The kernel log file has this snippet at the end:

    Feb 14 16:29:21 upstairs kernel: pci 0000:00:02.0: PCI INT A -> GSI 16 (level,
    low) -> IRQ 16

    and Xorg log file has:

    [mi] EQ overflowing. The server is probably stuck in an infinite loop.

    followed by many instances of thse two lines:

    [mi] mieqEnequeue: out-of-order valuator event; dropping.
    [mi] EQ overflowing. The server is probably stuck in an infinite loop.

    Xorg server is version 1.5.3 and xorg intel driver is version 2.7.1

    bzipped copies of the kernel and Xorg logs are attached but, please let me know
    if any additional diagnostics are needed.

    Thanks,

    Chris
