Hi! I'm running the Aug 23 snapshot on a Thinkpad T410, usually connected to an external display. Sometimes, when I resize a window while the display is set to a high resolution (e.g., 1920x1200 or 1600x1200), the screen "freezes" for a moment and the following messages appear on the console.
Aug 28 23:56:12 trav /bsd: error: [drm:pid12469:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung Aug 28 23:56:13 trav /bsd: error: [drm:pid12469:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung Aug 28 23:56:13 trav /bsd: error: [drm:pid556:i915_reset] *ERROR* GPU hanging too fast, declaring wedged! Aug 28 23:56:13 trav /bsd: error: [drm:pid556:i915_reset] *ERROR* Failed to reset chip. After that happens, XVideo output won't work anymore until I reboot. I can trigger this by wildly resizing, e.g., a firefox window for a couple of seconds, but it also sometimes happens during normal use. With a resolution of 1280x1024, I can resize all I want without problems. I've been noticing this problem since I got a larger monitor, so I don't know for which snapshots/releases this problem exists. Maybe the GPU is just too slow? However, in general, everything runs pretty smooth. Thanks to everyone taking the time to have a look at this! If you need some more information, please ask. dmesg: OpenBSD 5.6-current (GENERIC.MP) #342: Sat Aug 23 06:39:47 MDT 2014 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 4062691328 (3874MB) avail mem = 3945811968 (3763MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.6 @ 0xe0010 (78 entries) bios0: vendor LENOVO version "6IET79WW (1.39 )" date 07/15/2011 bios0: LENOVO 252225G acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT ECDT APIC MCFG HPET ASF!
