[Xen-devel] bug: kernel 2.6.37-12 READ FPDMA QUEUED

[Gerry Reno <greno@xxxxxxxxxxx>]

I've been trying to install a 2.6.37-12 kernel from kernel-ppa on one of
my Ubuntu machines without success.

It keeps giving errors like this:

    [ 9.115544] ata9: exception Emask 0x0 SAct 0xf SErr 0x0 action 0x10
    frozen
    [ 9.115550] ata9.00: failed command: READ FPDMA QUEUED
    [ 9.115556] ata9.00: cmd 60/04:00:

    [ 9.115557] res 40/00:18:d3:82:85/00:00:1f:00:00/40 Emask 0x4 (timeout)
    [ 9.115560] ata9.00: status: { DRDY }
    [ 9.115562] ata9.00: failed command: READ FPDMA QUEUED

I've searched and found some bugs referencing this type of problem and
followed some suggestions:

I added libata.force=noncq to the kernel boot line but it did not help.

My hardware is like this:

I've tested the hard drives with manufacturers surface test tools and
the drives show no errors.  Smartctl shows no errors after testing.

Is there some kernel switch I need to support this hardware w/2.6.37-12
kernels?

Gerry
