When trying to put some stress on qemu by running the xfs testsuite
I get the following:
debian:~/xfs-cmds/xfstests# sh check
[ 438.166822] SGI XFS with ACLs, security attributes, realtime, large block numbers, no debug enabled
[ 438.185557] SGI XFS Quota Management subsystem
[ 438.193150] hdb: task_no_data_intr: status=0x41 { DriveReady Error }
[ 438.194018] hdb: task_no_data_intr: error=0x04 { DriveStatusError }
[ 438.194195] ide: failed opcode was: 0x9d
and after that the kernel seems to hang. Qemu is emulating a piix3
device, and using the piix driver. This is on a pretty old kvm (version
28) because newer ones don't even compile.

Drive aborted the command. Thats all correct.

Old Qemu is not really a credible IDE emulation. The chances are that as
with all the libata bugs I close for qemu the problem is qemu. Please
file a bug with the qemu people.

kvm-28 is ancient and there have been IDE emulation fixes since. I am
not aware of issues building KVM either. The problems you reported a
month ago on kvm-devel have been fixed.

Agreed, this is very likely to be a QEMU issue (that may have already
been fixed).
