Dear all, since 4.4-rc (at least rc2 it was the first I tested), the Intel DRI is in very broken state. Hardware: Sony VAIO Pro 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Sony Corporation Device 90b6 Flags: bus master, fast devsel, latency 0, IRQ 40 Memory at f5c00000 (64-bit, non-prefetchable) [size=4M] Memory at e0000000 (64-bit, prefetchable) [size=256M] I/O ports at f000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [a4] PCI Advanced Features Kernel driver in use: i915 Symptoms: * font corruption sometime sets of glyphs, or practically all glyphs disappear related probably to bug https://bugs.freedesktop.org/show_bug.cgi?id=55500 I have sent some info there already, without response Currently my font displays some kind of strange symbols instead of an m ... looks a bit like a Kanji. * drm/i915 hang: GPU HANG: ecode 7:0:0x86d2bff9, in cinnamon [9300], reason: Ring hung, action: reset opened a new bug as advised https://bugs.freedesktop.org/show_bug.cgi?id=93279 several other hangs like that, reported only one * intelfb is dead switching to the console often leaves a black console Most of the time this happens after a suspend to ram and wake up, but not always. Let me know if there is anything else one might want to know Thanks Norbert ------------------------------------------------------------------------ PREINING, Norbert http://www.preining.info JAIST, Japan TeX Live & Debian Developer GPG: 0x860CDC13 fp: F7D8 A928 26E3 16A1 9FA0 ACF0 6CAC A448 860C DC13 ------------------------------------------------------------------------ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
