    Hello!

    The patch before, I told it always boots but the last two days I had
    much difficulties to boot. It was hard resetting and waiting a couple of
    times before bailing out with no mountable root FS.

    One time it was switched off three hours and the next time overnight, I
    powercyced a couple of times. If I am the only one experiencing this
    difficulties (am I the only one with this chipset/revision reporting?),
    shouldn't we consider this machine... broken? I change SATA cables from
    time to time, but these seem all to be okay. I mean, if it is really
    _that_ strange...

    Eh... I just bought a used opteron system with nf2/3. I will receive
    the machine tomorrow. Hopefully, I'll be able find out what the heck is
    going on here.

  3. Re: SATA Cold Boot problems on >2.6.25 with NV

    Hello Tejun!

    After my short reply I had a 2.6.27 running with

    [-- Attachment #2: sata_nv-nf2-hrst-debug-take2.patch --]

    fine so far. It bootet immediately at any time I powercycled the
    machine. Hot, cold and reboot seems to be no problem, no
    /var/log/messages flooding also.

    I just wanted to inform you, whatever the investigations result into, on
    _my_ machine this incarnation is just fine.

    Regards, Konsti

    Great. My test machine just confirmed the fix too (my first purchase
    was borked so I had to get another one so the delay). I'll forward the
    fix to upstream.

    Thanks a lot.

    No Problem at all. If something gets borked - which absolutely is
    allowed to happen - I have fun to sort this out.
