BSW: gpu hang on kernel (debian package) >= linux-image-5.5.0-2-amd64
dmesg dump:
2020-08-17T15:51:29,240687-07:00 i915 0000:00:02.0: GPU HANG: ecode 8:1:85dffffb, in arb_texture_buf [20052]
Card error output attached
Steps to reprod:
1) install debian-testing image on a bsw machine (the default kernel on the debian testing image is 5.7.0 so you can just use that)
2) build and install mesa 20.2 staging on the system as well as master branch of piglit.
SHAs that were tested:
mesa=b454e445796
piglit=b7836091a
3) run the entire piglit suite and monitor dmesg output (dmesg -w) for video card errors. The should occur after ~7000 tests in (maybe 10 or so minutes through the run)
All of my testing was done in the mesa CI.
