After googling I found this to be a common problem when some error message is flooding /var/log/messages. Apparently it is ok to killall kerneloops; I did, and this does of course stop it from eating cpu. But it doesn't solve the basic problem, what is flooding the messages file? In my case it is huge number of lines: Nov 29 13:27:04 localhost kernel: [drm:mga_dma_reset] *ERROR* mga_dma_reset called without lock held, held 0 owner f4041ae0 f4041ae0 Nov 29 13:27:04 localhost kernel: [drm:mga_dma_flush] *ERROR* mga_dma_flush called without lock held, held 0 owner f4041ae0 f4041ae0 Nov 29 13:27:04 localhost kernel: [drm:mga_dma_reset] *ERROR* mga_dma_reset called without lock held, held 0 owner f4041ae0 f4041ae0 Nov 29 13:27:04 localhost kernel: [drm:mga_dma_flush] *ERROR* mga_dma_flush called without lock held, held 0 owner f4041ae0 f4041ae0 Nov 29 13:27:04 localhost kernel: [drm:mga_dma_reset] *ERROR* mga_dma_reset called without lock held, held 0 owner f4041ae0 f4041ae0 Nov 29 13:27:04 localhost kernel: [drm:mga_dma_flush] *ERROR* mga_dma_flush called without lock held, held 0 owner f4041ae0 f4041ae0 Nov 29 13:27:04 localhost kernel: [drm:mga_dma_reset] *ERROR* mga_dma_reset called without lock held, held 0 owner f4041ae0 f4041ae0 Nov 29 13:27:04 localhost kernel: [drm:mga_dma_flush] *ERROR* mga_dma_flush called without lock held, held 0 owner f4041ae0 f4041ae0 Any advice on this? Might it be tied to my somewhat frequent X-freezes? As it stands now I will still continue to get the large messages file requiring me to truncate the file, every day or so Jack -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
