Using sys-fs/lvm2-2.02.103, issuing a command such as lvcreate --type raid5 ... Results in lvcreate getting stuck in a DM_TABLE_LOAD syscall that never returns. I tried several different kernel versions. sys-kernel/gentoo-sources-3.10.17 - WORKS sys-kernel/gentoo-sources-3.10.20 - WORKS sys-kernel/gentoo-sources-3.11.8 - WORKS sys-kernel/gentoo-sources-3.11.9 - WORKS sys-kernel/gentoo-sources-3.12.0 - FAILS sys-kernel/gentoo-sources-3.12.1 - FAILS
I don't think my previous comment about DM_TABLE_LOAD was correct, I think strace locked up before it finished writing what had happened.
