Message-ID: <1233910614.23431.18.camel@marge.simson.net> (raw)
Greetings,
Futzing with kerneltop this morning, I fired up amarok to give it
something light to monitor while I hunt missing events. Something bad
happened, and when I finally (SysRq-E took minutes) got control of box
back, dmesg was full of a steady stream of the below.
That warning can be kinda unfriendly.
