Warning at block/genhd.c:1556 disk_clear_events

From: Meelis Roos
Date: Mon May 02 2011 - 05:59:22 EST


Just tried 2.6.39-rc5-00130-g3fd9952 on amd64 with sata disks attached
to sata_nv. This warning happened 1 hour after boot with normal desktop
usage. What udisks-daemon did, I do not know - I do not remember
inserting any USB disksk to the system.
