Crash dump from hang while using Discord.

On my laptop with Intel graphics (i5-5200U), I have had issues with occasional hanging when using various programs. This has been happening for well over a year, but I haven't been able to resolve it. Anyway, I checked journalctl and I was told to file a new bug report, so here I am. Typically the programs that cause a hang are some kind of web browser or web client (e.g. Discord, Slack, and Chromium). Sometimes it's an isolated hang for a few seconds, and other times several will happen in a row, often leading me to close the program. Recently, some freezes have been unrecoverable, requiring a system restart. These have been especially hard to debug, as journalctl provides no useful logging when I check the end of the logs for the previous boot after restarting. My intuition says that this might be an unrelated problem however, as it only seems to happen when I am using my bluetooth headphones. That might just be a coincidence though. Anyways, I have attached the crash dump, so hopefully that will provide more insight than I have already.

rcs0 command stream:
  IDLE?: no
  START: 0x0104f000
  HEAD:  0x00600248 [0x000001f8]
  TAIL:  0x00000300 [0x00000248, 0x00000288]
  CTL:   0x00003001

  IPEIR: 0x00000000
  IPEHR: 0x7b000005
  INSTDONE: 0xffdfbefb

IPEHR: 0x7b000005 shows as Instruction_3DPRIMITIVE (from bspec). Assuming this is a mesa bug. Closing this issue as NOTOURBUG.
