Please flag this patch for stable.
This patch resolves a serious problem on IBM Power systems at least.
An (apparently constant) series of invalid iotags cause a series of
SCSI command aborts that escalates into host reset, which fails too,
bringing the adapter offline.
And it takes forever to boot, as udev waits on the initial SCSI I/O.
Thank you.
