Started recently on Nightly again with build id 20200710094819 at a low rate. But reports from other channels as well. Bug 1379408 had the same signature but was closed as no longer appearing several years ago. For Nightly, all crashes have adapter_device_id = 0x0126, and several other correlations.

bug 1692399 has a ton of these crashes. Looks like many related to AMDRadeonX4000GLDriver

The crash rate doubled for both Firefox and Thunderbird in early May https://crash-stats.mozilla.org/signature/?signature=__pthread_kill%20%7C%20abort%20%7C%20gpusGenerateCrashLog.cold.1&date=%3E%3D2021-03-19T08%3A41%3A00.000Z&date=%3C2021-06-19T08%3A41%3A00.000Z#graphs

I've put bug 1692399 in the triage list so it gets a some attention during the next gfx triage meeting.

Closing because no crashes reported for 12 weeks.
