    SubjectRe: pci bridge 0000:00:1c.1 compaq nc8230 laptop
    Date
    Hi All,

    Just a quick update re the pci bridge 0000:00:1c.1 problem.

    I have tried to 2.6.13.4 without the APCI and Yentra modules. It
    boots fine with APCI and Yentra disabled. TPM still not found on
    nc8230, but one step closer.

    I have now tried up to 2.6.13.4 using the default kernel config and it
    still crashes at boot. i.e.
    bridge 0000:00:1c.1 then halt.


    Linux version 2.6.13.4 (root@localhost.localdomain) (gcc version 3.3.3
    20040412 (Red Hat Linux 3.3.3-7)) #2 Thu Oct 20 07:50:16 BST 2005

    I'd solve this problem but my Linux kernel coding skills are aren't
