Just got another one..

Jul 25 13:30:47 elfi kernel: ad4: FAILURE - device detached
Jul 25 13:30:47 elfi kernel: subdisk4: detached
Jul 25 13:30:47 elfi kernel: ad4: detached

ad4s1 disconnected.
Jul 25 13:30:47 elfi kernel: g_vfs_done():mirror/gm0s1f[READ 
(offset=46318008320, length=2048)]error = 6

(offset=77269614592, length=16384)]error = 6

6 days uptime when this occured... Both disks are tested with  
PowerMax without a single problem (same with smartctl), both SATA  
cables are new. So the only hwproblem that I cant rule out would be  
the mobo, but that is quite new too...

Solutions? Try RELENG_6 as recommended earlier?

Thanks
