Thanks for your kind help , Bernd . setting /sys/block/sdX(c~j)/device/queue_depth to 1 unfortuantely didn't solve the issue . I put the following in the end of the boot line : mpt2sas.disable_watchdog=1 mpt2sas.max_queue_depth=1 mpt2sas.max_sgl_entries=64 mpt2sas.max_sectors=64 However , the OS doesn't see the controllers anymore . So I had to remove these entries from the boot line . Thank you . -- You are receiving this mail because: You are watching the assignee of the bug.
