I'll just add a big ack for these two patches. I have been using these extensively now for a couple 
of weeks on a 14 drive array spread over 12 Maxtor Drives on Promise SATA150TX4 Controllers and 1 
WD2500BB on a VIA controller by way of an SIL PATA->SATA bridge polling all drives hourly for full 
SMART stats and running daily self tests while also testing heavy drive usage patterns and manual 
SMART polling and have not encountered any data corruption.

Read that as "I have tried really, really hard to break it and as yet been unable to".

Regards,
Brad

Is your system SMP ? I'm actively tracking a problem now with
pass-thru behaviour (via /dev/sg* ) on SMP systems.

Symptom is a system freeze after a few messages like
this:

ata3: command 0x34 timeout, stat 0x58 host_stat 0x0
ata2: command 0x24 timeout, stat 0x58 host_stat 0x0
ata3: status=0x58 { DriveReady SeekComplete <4>ATA: abnormal status 0x58 on port 0xF8A3CCC7
ata2: status=0x58 { DriveReady SeekComplete DataRequest }
DataReq

This particular example is of a Read Sectors command pending
on one drive and Write Sectors on another. Don't know if it
is the pio state machine not being SMP-safe, or what just yet.

Nope, sorry. Only lowly UP here.

I can confirm that there is some sort of problem with
PIO and SMP. Either exercising only DMA commands, or booting
with maxcpus=1 avoids the problem. At present, I suspect
the PIO task and/or state machine, but I'm still investigating.

I doubt this problem will occur unless you have concurrent
PIO access to different controllers on an SMP system.

I'd just like to give this the "two thumbs up". I'm getting great results from the SMART support 
(Thanks Andy and John!)

Yeah! the PATA controller is seen. I'll shutdown and stick a disk on the
controller and give it a whirl.

Thanks Eric and Jeff
