I'm running Intel GM45 and UXA (not SNA), and I got the same syslog output.

2013-06-20T17:26:07.827440-04:00 mike-laptop kernel: [ 1320.857209] [drm] not
enough stolen space for compressed buffer (need 4194304 bytes), disabling

you may be able to increase stolen memory size in the BIOS to avoid this

During boot, however, stolen memory size is sufficiently large.

Any ideas what's happening?

Thanks
