Hi, libblkid and friends stopped detecting my swap partition on my Ubuntu laptop that I'm running the bleeding edge natty repo on (e.g. wipefs shows nothing, and I can't get a uuid from blkid). It's running 2.6.37-2 kernel and this bug persists in the latest git from git.kernel.org/pub/scm/utils/util-linux-ng version 07b33...40a8 I think this is due to the change in the hibernate signature from this patch: http://www.gossamer-threads.com/lists/linux/kernel/1283551 If I look at the header of my partition I see: 0007740 027 ! \0 \0 \0 \0 \0 \0 001 \0 \0 \0 S W A P 17 21 00 00 00 00 00 00 01 00 00 00 53 57 41 50 0007760 S P A C E 2 L I N H I B 0 0 0 1 53 50 41 43 45 32 4c 49 4e 48 49 42 30 30 30 31 Looking at shlibs/blkid/src/superblocks/swap.c I see it's looking for the SWAPSPACE2 signature at the address where I ahve LINHIB0001. What's the right fix here? Is it to add the LINHIB0001 to the swsuspend match table? Or is it more subtle - the SWAPSPACE2 in my header above is 10 bytes earlier than the one that util-linux is looking for. How are these headers supposed to work - should that LINHIB0001 still be there or is it due to a failed resume? I assume libblkid should still find it even in that case? Here is an Ubuntu bug that I filled in for it: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/682176 Thanks in advance, Dave (please cc since I'm not subscribed). -- -----Open up your eyes, open up your mind, open up your code ------- / Dr. David Alan Gilbert | Running GNU/Linux | Happy \ \ gro.gilbert @ treblig.org | | In Hex / \ _________________________|_____ http://www.treblig.org |_______/ -- To unsubscribe from this list: send the line "unsubscribe util-linux-ng" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
