Ethan confirmed that it's 1095:3114. Arghhh.... Maybe we should keep m15w quirk for 3114's for the time being? Better be slow than hang. Whatever bug the m15w quirk was hiding.


A generic 'slow_down_io' module option is reasonable.

It is not appropriate to apply mod15write quirk to hardware that isn't affected by the chip bug.

A better solution is to write a 311x-specific interrupt handler.


Hello, Jeff.  Hello, Carlos.

I bought a sii3114 controller yesterday and took out my ST3120026AS for testing. The drive times out during a WRITE_EXT, and locks up.

* The ST3120026AS works perfectly on a VIA controller.
* The sii3114 controller works perfectly with Maxtor 6B080M0 drives.

I don't know. It acts and smells like m15w problem. What are the odds of having the same symptom on the same combination?

Also, I've asked one of my friends who has a sii3512 onboard controller and an affected seagate drive to test. The harddisk works on 2.6.13 with the quirk, but it freezes on 2.6.14. m15w affected seagate drives does _NOT_ work on 3512 and 3114 on 2.6.14, be it m15w or something else.
