Comment 20 for bug 263160

I believe I also have this problem with Jaunty (9.04) running 2.6.28-11-server.

I am using 6 Seagate 1.5TB Disks (that do NOT have the notorious freezing firmware) and Promise SATA controllers, under heavy load i get ATA resets and 2 drives drop out of my raid.

Drive Info:

 Model Number: ST31500341AS
 Serial Number: 9VS1F7AR
 Firmware Revision: CC1H
 Transport: Serial

Controllers:

00:08.0 Mass storage controller: Promise Technology, Inc. PDC40718 (SATA 300 TX4) (rev 02)
00:09.0 Mass storage controller: Promise Technology, Inc. PDC40718 (SATA 300 TX4) (rev 02)

Rebooting and recreating the md0 restores the raid (albeit with a 3 day to run recovery).
