[hoping I persuaded gmail to get my old text-only email settings back, grrr]
Noticed that my root fs was filling up, and found out that /var/log/messages was
approaching 2GB of space, most of which were as per $subject. To give an idea
of the magnitude, here's a snippet from a saved sample of /var/log/messages:
[root@xbox log]# grep "Disabling PP" messages.save.head |head -1
Apr 15 03:44:10 xbox kernel: [ 3.115126] [drm] Disabling PPGTT
because VT-d is on
[root@xbox log]# grep "Disabling PP" messages.save.head |tail -1
Apr 15 03:45:50 xbox kernel: [ 130.165219] [drm] Disabling PPGTT
because VT-d is on
[root@xbox log]# grep -c "Disabling PP" messages.save.head
610
Or from the dmesg ring:
[root@xbox log]# dmesg|head
[22446.690572] [drm] Disabling PPGTT because VT-d is on
[22446.690616] [drm] Disabling PPGTT because VT-d is on
[22446.704560] [drm] Disabling PPGTT because VT-d is on
[22446.706747] [drm] Disabling PPGTT because VT-d is on
[22446.720202] [drm] Disabling PPGTT because VT-d is on
[22446.722447] [drm] Disabling PPGTT because VT-d is on
[22446.724850] [drm] Disabling PPGTT because VT-d is on
[22446.727268] [drm] Disabling PPGTT because VT-d is on
[22446.733052] [drm] Disabling PPGTT because VT-d is on
[22446.735319] [drm] Disabling PPGTT because VT-d is on
Are there patches for this issue, or is a workaround available to prevent a
filesystem full condition on my root fs?
This is on a Dell Latitude E6420 laptop, Fedora 19 x86_64, onboard
Intel video card... yes, I have an old A08 BIOS, but I've never seen
this issue while regularly updating my mainline kernel weekly or so...
Available for more details if needed, thanks in advance,

forwarding from my lkml post as probably more appropriate to send this here...

Yup, but just adding more cc's is preferred. I've re-added lkml for
reference. Bug is fairly obvious regression in 3.15, patch is on the way.
