I suspect a kernel bug ('bio->bi_idx = bio_src->bi_idx'
missing from bio_clone in fs/bio.c) found and fixed upstream in 2.6.13-rc4.

Description of problem: When I reboot my workstation (which uses an lvm2 over software RAID5 setup), lvm2 randomly segfaults, causing a root partition mount failure and in-turn a kernel panic (attempt to kill init). Sadly enough, while I copied the segfault error code (by hand), I doubt that it'll prove to be too useful. Please let me know how I can supply further debug information. Version-Release number of selected component (if applicable): lvm2-2.01.08-2.1 kernel-2.6.12-1.1398_FC4smp (Also verfied with older versions). How reproducible: Random. Steps to Reproduce: 1. Reboot machine. (reboot -f seems to reproduce it better.) 2. LVM2 segfaults. Actual results: " (Copied it by hand... hope I didn't screw anything...) lvm[568]: segfaults at 0000000000000000 rip 00000000004001a8 rsp 0007ffffffcd2790 error 6. ERROR: /bin/lvm2 exited normally with value 0! (pid 568) " After wards the sysinit tried to mount the root partition (and fails), tries to open console (fails again) and tries dup'ing the different std handles (fails yet again). When all fails, init dies and the kernel panics. Expected results: Normal boot.
