2.6.0-test7 with reiser4, mount and /sbin/lilo unkillable in D state.

[Steven Cole]

Greetings all,

Here's one I haven't seen before.

After getting an oops with while mounting a freshly made
reiser4 partition, I recompiled with CONFIG_KALLSYMS and
then lilo hung up.  Both process 825 and 4436 are unkillable
with kill -9 in the D state.

The box is still up for now. If I can't get this fixed in the next hour,
it'll have to wait until Monday.  It's a test box, so that's OK.

Any advice?

Get a sysrq T dump if possible.
