Were you able to reproduce it on your own SKL, or does it only happen on the CI ones? On our own SKL. I haven't seen any flaky tests in this category in Mesa i965 CI. We run the GL46 variants of the tests, on Linux 4.18. Usually SKL and KBL have identical regression patterns, so it is surprising that you can't reproduce the regression on KBL. Are there differences between those systems (eg kernel or other sw configuration)? (In reply to Mark Janes from comment #4) > I haven't seen any flaky tests in this category in Mesa i965 CI.

Are there differences > between those systems (eg kernel or other sw configuration)? Yeah, weird. Since we use docker, the SW stack is the same, with the exception of the services provided by the host system. Namely, the kernel and X server versions. Additionally, all hour host systems are running Debian Buster but I've actually realized that our KBL is using also Linux 4.18. I'm just now running a pass in the SKL box with the same 4.18 kernel. Let's see what comes out. Created attachment 143129 [details]

Checked with 2 other similar NUCs with SKL and I cannot reproduce the problem. They are running with the same Debian distro and kernel version. Closing as RESOLVED WORKSFORME while still trying to figure out which could be the difference. I'll reopen/report if I find something else. (In reply to Andrés Gómez García from comment #9) > Checked with 2 other similar NUCs with SKL and I cannot reproduce the > problem. FTR, checked: * BIOS: same on all of them. * CPU: same on all of them. * Mother board: same on all of them. * RAM: 2 with 16Gb, 1 with 8Gb (all from the same maker). The failing NUC has 16Gb, there other one with 16Gb, however, is working. Passed the cts-runner execution with 2 same NUCs but with the disks swapped. Both pass. I cannot reproduce. This looks really like a ghost. No clue what happened. We just found out yesterday that persistent Mesa i965 CI issues were caused by a bug in kernel 4.18 and older:
https://patchwork.freedesktop.org/patch/252573/
I wouldn't run any graphics workloads on intel systems with kernel older than 4.19.
