Tejun,
While working on the new hdparm (version 7.0, released today),
I ran into trouble when a buggy SG_IO/ATA_16 packet caused
the libata EH to get confused.
I triggered this by accident, issuing an IDENTIFY command
which incorrectly specified ATA_PROT_NODATA. My error, for sure,
but libata never recovered from the "stuck DRQ bit" that resulted.
In the IDE driver, we had code to try and cope with stuck DRQ,
by just looping and reading from the data port a few times.
That could have been done better, but it worked a lot of the time,
back in those simpler days.
I don't know what you try in libata-eh, but perhaps it can be tweaked?
Below is the 'dmesg' from that system before I hit the big red button.
I can also supply a program that will generate this lockup on demand,
for testing purposes.
Cheers
Mark
