Has been triggered in linus-v4.12, linux-next and DRM-Tip builds, just fastest to hit on linux-next. - 60sec timeout and panic from watchdog on most of the other hosts This might be controller / disk issue too, but I can't read the log well enough to tell if that's the case. This latter issue is probably what Marta was tracking, and it's much harder to reproduce manually. IGT fast-feedback runs seem to hit it very regularly, for some reason. There's nothing magical in what CI is doing: Open SSH connection which is kept up, start Jenkins-CI Java client, this starts IGT run through a shell script. This all within ~30 seconds of testhost OpenSSH starting up. Collected traces from todays 20170711 run, very different hosts: https://intel-gfx-ci.01.org/CI/next-20170711/fi-ivb-3520m/dmesg-149974972_Panic_1.log fi-ivb-3520m: HP Elitebook 8440p laptop with Intel SSD 520 https://intel-gfx-ci.01.org/CI/next-20170711/fi-ivb-3770/dmesg-149974971_Panic_1.log fi-ivb-3770: HP Pro 3500 desktop with Intel SSD 530 https://intel-gfx-ci.01.org/CI/next-20170711/fi-hsw-4770r/dmesg-149974972_Panic_1.log fi-hsw-4770r: Gigabyte "Brixbox" NUC with Samsung SSD 840 EVO https://intel-gfx-ci.01.org/CI/next-20170711/fi-bxt-j4205/dmesg-149974980_Panic_1.log fi-bxt-j4205: Asrock J4205-ITX MB with Intel SSD 530 I'll continue to look for a way to reproduce this issue more easily. -- You are receiving this mail because: You are watching the assignee of the bug.
