If this is a pci based card, then it is trying to allocate 32MB of contiguous physical ram when the drm device is opened. This usually succeeds the first time that the driver opens the device, but later, after memory has become fragmented, this can become an issue. As I have mentioned, I have code that reworks this whole process and I'll try and make a patch available soon, but my I don't have a lot of time now, so it might be the weekend before I can rebase the code and get a clean patch. robert. > [1] http://tx97.net/~magv/dmesg-t40.80-p2.txt > _______________________________________________ > freebsd-x11@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-x11 > To unsubscribe, send any mail to "freebsd-x11-unsubscribe@freebsd.org" -- Robert Noland <rnoland@FreeBSD.org> FreeBSD
