Subject: kernel unaligned accesses on 2.6.29.
Date: Tue, 24 Mar 2009 17:28:57 +0000 [thread overview]
Message-ID: <20090324172856.GA8908@sgi.com> (raw)
I just built and booted an ia64 2.6.29 kernel. While accessing NFS
filesystems, I occassionally get:
kernel unaligned access to 0xe00007bc3b8f67b9, ip=0xa00000020a61e370
kernel unaligned access to 0xe00007bc3b8f67b1, ip=0xa00000020a61e3d1
grep a00000020a61 /proc/modules
lockd 146448 1 nfs, Live 0xa00000020a610000
These come in pairs. I tracked it down to the lockd.ko kernel module
and then objdump'd to find we are in:
nsm_get_handle
nsm_init_private():
/data/lwork/attica2/holt/git-linus/v2.6.29/fs/lockd/mon.c:280
e370: 0b 00 98 68 98 11 [MMI] st8 [r52]=r38;;
