Now that we have found the ata_op code of 0x35, what does this mean? Is it
generated from a bad FUA/unsupported command from the kernel/SATA driver?

Please read the FAQ at http://www.tux.org/lkml/
In /usr/src/linux/include/linux/ata.h:
ATA_CMD_WRITE_EXT = 0x35,
Perhaps these drives do not support this command or do not support it
properly?
Any idea, Jeff/Alan?
Justin.
Here are all the errors (when reading/writing heavily):
[4294810.556000] ata_gen_fixed_sense: failed ata_op=0x35

Jeff/Mark, from these errors can we reach a consensus as to the cause of
these errors and how to eliminate the problem?
Thanks,
Justin.
