I'm also willing to help. The card is not on a production server and the disks connected to the card do not contain any valuable data so I can make any test wanted.
When the problem occurs it seems the devices (disks) are hosed. Deleting them from the system (echo 1 > /sys/block/sdh/device/delete), removing the mvsas module (rmmod -f) and reloading it doesn't work. The card seems correctly initialised after reloading the module, it correctly responds to commands (in /sys/class/sas_phy/ and sas_ports, I can reset ports/phys, I can ask for a rescan of disks). But the disks themselves do not seem to answer to the scan and are not detected, all I get is :
Oct 13 15:17:33 almery kernel: [29162.468218] sas: sas_ata_phy_reset: Found ATA device.

Oct 13 15:17:33 almery kernel: [29162.474627] scsi_alloc_sdev: Allocation failure during SCSI scanning, some SCSI devices might not be configured
Is there a way to get a disk to reinitialize itself without a reboot ?
Drives are SAMSUNG HD501LJ Linux almery 2.6.31.1-vs2.3.0.36.14 #7 SMP Mon Oct 12 12:58:07 CEST 2009 x86_64 GNU/Linux with or withous vserver patch applied : same problem, kernel not tainted.
The problem occurs also when the disks are not in an md array.
