>Description:
There are two i915 PRs when searching for "heartbeat":
- This one http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=57440 is closed as it only seen from UEFI boots but not from BIOS boots. My computer has a BIOS only and so my problem must different.
- The patch from http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=57268 is Haswell specific.
Below is my PR for NetBSD 10_R4 on Sandy Bridge (Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz, id 0x206a7)
# lspci -s 00:02.0
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
xorg.conf
Option "AccelMethod" "uax"
Below heartbeat not ticking error happens after running X for 5 days. There were occasional graphics glitches the days and in particular the hours before this error (pixel noise: some segments of the screen showed random pixels for a few minutes).

I had also issues with the i915 driver on NetBSD 9. I spent a few hours debugging it, but realized a life-time is not enough.
Is there a recommended external GPU for NetBSD? Something that just works without any graphic glitches? Nothing fancy, just something for watching videos with mpv a/o ffplay, and firefox/youtube?
