    When booting our kernel in blob (using the build and boot instructions given on the web and at http://projects.buici.com/) we get the following errors:

    Bad page state at free_hot_cold_page (in process 'swapper', page c026ec60)
    flags:0x00000080 mapping:00000000 mapcount:0 count:0
    Backtrace:
    [<c0022c20>] ($a+0x0/0x14) from [<c004cb0c>] (bad_page+0x64/0x94)
    [<c004caa8>] (bad_page+0x0/0x94) from [<c004d214>] (free_hot_cold_page+0x8c/0x16

    ...
    Followed by a stack dump and then:

    <1>Unable to handle kernel paging request at virtual address 6974b6
    0f
    pgd = c0004000
    [6974b60f] *pgd=00000000

    Flags: nzCv IRQs off FIQs on Mode SVC_32 Segment kernel

    Followed by

    <0>Kernel panic: Aiee, killing interrupt handler!
    In interrupt handler - not syncing


    We are relatively new to this. Do these errors imply that we have bad HW?

    Thanks.

    cobranov,

    I would suggest emailing Marc Singer about these issues since they're based on his Linux port for the LH7A400-10.
