I did get the 18.00.00.00 driver to compile under 3.13.6, however it gave me its own problems: as I attempted to dd if="$f" of="$f" bs=65536 across every disk in the system simultaneously, the system would, after 20-30 minutes, lock solid. (This process proceeded fine if of=/dev/null; I'm doing this to find disks that I know have sector errors.) I have no dmesg output. Further, modprobe -r was _very_ slow on this driver, eventually printing to dmesg a trace including "warn_slowpath_fmt". Attached is a basic patch to get the new LSI driver to compile under 3.13.6, but no guarantees as to the quality of anything. -- You are receiving this mail because: You are watching the assignee of the bug.
