I'm seeing very similar hangs on -mmotm-11-17 as well. I've hit it 3 times today, all while disk activity was moderately heavy (things like 'yum update', or a 'find . | xargs grep', and so on). Managed to catch one while netconsole was active - I didn't have any messages for bugs/warns/oopsen. Apparently, somebody is holding a lock. (I also have an alt-sysrq-t from this incident, but that's about 10 times as big, didn't want to abuse vger too much.. ;) [ 3932.912494] SysRq : Show Blocked State [ 3932.913465] task PC stack pid father [ 3932.913465] pdflush D ffff88007e247cf0 5776 303 2 [ 3932.913465] ffff88007e247c50 0000000000000002 ffff88007e247bb0 ffff88007dcf54d8 [ 3932.913465] ffff88007e247c00 ffffffff8081c780 ffffffff8081c780 ffff88007f269040 [ 3932.913465] ffff88007f232040 ffff88007f269398 000000007e247be0 ffff88007f269398 [ 3932.913465] Call Trace: [ 3932.913465] [] ?
