Hi there, I don't know if anyone else has been having similar issues. On the ThinkPad T420 (i5-2540M, Sandybridge), the drm-kmod (drm-fbsd12.0-kmod-4.16.g20181215) hangs like this, infrequently, but often enough on GPU applications: [drm] GPU HANG: ecode 6:0:0x61f7fffd, in chrome [100694], reason: Hang on rcs0, action: reset drmn0: Resetting chip after gpu hang last message repeated 1 times drmn0: i915_reset_device timed out, cancelling all in-flight rendering. It doesn't just hang with Chromium, it hangs on other apps as well. Tricky thing is that things otherwise seem to work, and I haven't figured out how to reliably reproduce the hang. Particularly, https://wiki.freebsd.org/Graphics/Intel-GPU-Matrix claims that other people have working Ivy Bridge with drm-kmod; maybe that has to be drm-kmod-legacy until I figure out what's going on. Should I create a PR, or wait until I have more info? -- Kevin Zheng [email protected] | [email protected] | PGP: 0xC22E1090 _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-x11 To unsubscribe, send any mail to "[email protected]"
