There are similar same unaligned accesses in the kernel part. I have a patch attached, that should fix the complete issue, although I can not test it... When you test it, please also test the netlink packets from kernel to userspace as well. I.e. drbdsetup /dev/drbd0 events, drbdsetup /dev/drbd0 show, etc... -phil -- : Dipl-Ing Philipp Reisner : LINBIT | Your Way to High Availability : Tel: +43-1-8178292-50, Fax: +43-1-8178292-82 : http://www.linbit.com DRBD(R) and LINBIT(R) are registered trademarks of LINBIT, Austria. -------------- next part -------------- A non-text attachment was scrubbed...
