Hi,

I've got regular device resets on my harddrives. They have been there all the time since I bought the hardware. First used with 2.6.23 kernel with libata-tj patch and then with 2.6.24 without any patches and now with the 2.6.25 kernel and always got device resets.

The resets hang all disk activity for about 10 seconds and sometimes trigger a rebuild of my software raid5 array which are my greatest concern.

The storage controller are a Lycom 64-105e PCI-X eSATA adapter (Silicon Image 3124 chip) with three Lycom ST126RM port multipliers (Silicon Image 3726 chip) and a total of 13 harddrives, 10 samsung, 2 western digital and one Seagate.

Here's a cut from dmesg when the problem occur:

The problem almost only occur when I write files to the drives. Sometimes it can go over 10 GB and sometimes only a few MB between the resets.

Don't know what information is necessary for you but.
