Something fishy with framebuffer takeover from BIOS <7>[ 12.661656] [drm:drm_setup_crtcs] looking for preferred mode on connector 83 0 <7>[ 12.661661] [drm:drm_setup_crtcs] found mode 3840x2160 <7>[ 12.661666] [drm:drm_setup_crtcs] looking for cmdline mode on connector 101 <7>[ 12.661671] [drm:drm_setup_crtcs] looking for preferred mode on connector 101 0 <7>[ 12.661675] [drm:drm_setup_crtcs] found mode 1920x1080 <7>[ 12.661681] [drm:drm_setup_crtcs] picking CRTCs for 8192x8192 config <7>[ 12.664943] [drm:drm_setup_crtcs] desired mode 3840x2160 set on crtc 45 (0,0) <7>[ 12.664965] [drm:drm_setup_crtcs] desired mode 1920x1080 set on crtc 63 (0,0) <7>[ 12.665080] [drm:intelfb_create [i915]] re-using BIOS fb <7>[ 12.665274] [drm:intelfb_create [i915]] allocated 1920x1080 fb: 0x00000000 instead of which we should throw away it and create a new one, followed by pruning the eDP mode during fbdev probing: <7>[ 12.691895] [drm:drm_mode_debug_printmodeline] Modeline 84:"3840x2160" 60 533250 3840 3888 3920 4000 2160 2163 2168 2222 0x48 0xa <7>[ 12.691901] [drm:drm_mode_prune_invalid] Not using 3840x2160 mode: VIRTUAL_X which leads to no modes returned to the test. Looks like the test should do a full reprobe, but instead it gets the cached version of the previously pruned mode list. I'm unable to reproduce this on latest drm-tip with Linux kernel 5.0. The failure was last seen 49 days ago and the test has been passing without any warnings since then. Last seen this issue drmtip_204 (1 month, 3 weeks / 784 runs ago). The frequency of this bug occurrence is once in 23-933 runs or 1-2 months. We can wait for next 2 months and close this bug if this doesn't occur again. The reproduction rate of this issue is once in10.8 drmtip runs. Last seen on drmtip 204 and current run is 336. Closing this issue as WORKSFORME. The CI Bug Log issue associated to this bug has been archived. New failures matching the above filters will not be associated to this bug anymore. |
