Last night I recompiled with your first patch and left the machine
running - this morning it was frozen again :(

But although the machine froze I dont see the BUG's in the kernel log.
So honestly I'm wondering if that freezing is just a coincidence with
the bug you found since I didnt see a BUG... However I could run the
non-rt kernel for 13 days without freeze but cant run the -rt- kernel
without freezing for more than a few hours. Do you think think the bug
could cause that?
I need to run the non-rt today to get some work done and I'll run the
-rt- with the new patch this evening if thats ok.
The other "weird" errors are there, but I've just rebooted to the non-
rt kernel and I'm getting those "ERROR block_reap:328: [bandwidth] bad
exit code 1" a lot still... but searching specifically on those is
pointing to i3blocks... indeed killing i3blocks does stop them, so
something in my i3blocks config is screwy. Woops! I was confused
because the logs show them being trapped by gdm3.
Many thanks for your help and brilliant code.
