Subject: linux-next - WARNING: at fs/block_dev.c:824 bd_link_disk_holder+0x92/0x1ac()
Date: Wed, 12 Jan 2011 12:34:33 -0500 [thread overview]
Message-ID: <16069.1294853673@localhost> (raw)
[-- Attachment #1: Type: text/plain, Size: 1998 bytes --]
Seen in a boot of yesterday's linux-next. The 'W' flag was due to the
already-reported 'WARNING: at kernel/workqueue.c:1202 worker_enter_idle'.
Not sure if it's a block_dev or dm/LVM issue, so I'm cc:'ing both groups. I wonder
if the fact I still have 'CONFIG_DEVTMPFS=n' is involved (it's apparently ticking off
dracut before and after the warning).

[ 16.892282] dracut: The link /dev/vg_blackice/opt should had been created by udev but it was not found. Falling back to direct link creation.
