I finally got around to testing 2.6.17.4 with libata-tj-stable-20060710.
Hardware: ICH7R in ahci mode + WD5000YS's.
EH: much, much better. Before the patch it seemed like errors were
only printed to dmesg but never handed up to any layer above. Now md
actually fails the disk when I pull the (power) plug. I'll try my bad
cable once I can find it.
Hotplug: Unplugging was fine, took about 15s until the driver gave up
on the disk. After re-plugging the driver had to hard-reset the port
once to get the disk back, though that might be by design.
The fact that the disk had changed minor numbers after it was plugged
back in bugs me a bit. (was sdc before, sde after). Additionally udev
removed the sdc device file, so I had to manually recreate it to be
able to remove the 'faulty' disk from its md array.
Thanks for a great patch! I just hope it doesn't eat my data :)
And thank you for testing!
