I hope I'm doing it right. According to "git bisect," your patch 10db10d144c0248f285242f79daf6b9de6b00a62 is the first bad commit before a regression which affects my ServeRAID II controller. I get segfault running ipssend, which is the program used to interrogate and configure the SCSI RAID controller. ipssend[5949]: segfault at 20202020 ip b7ece8b1 sp bfce1d1c error 6 in libc-2.9.so[b7e55000+15c000] Here's what git output on the final bisect: commit 10db10d144c0248f285242f79daf6b9de6b00a62 Author: FUJITA Tomonori Date: Fri Aug 29 12:32:18 2008 +0200 sg: convert the indirect IO path to use the block layer This patch converts the indirect IO path (including mmap IO and old struct sg_header) to use the block layer functions (blk_get_request, blk_execute_rq_nowait, blk_rq_map_user, etc) instead of scsi_execute_async().
