This test is opening every entry in /sys/kernel/debug/dri/* and reading it. DebugFS are meant to be used by developers and does not constitute a stable ABI. The entries are radable only by the root. Occasional (every few months) crashes by reading it across the whole farm of machines have no impact on users and very small impact on the CI. Lowering the priority to medium for now. Most of the failures I've seen in the past are caused by broken structure traversal, usually because of insufficient locking. Those crashes are hard to fight as we can only hope that we will get pstore having a relevant backtrace to even know which entry to investigate. Stale link, we have no clue where the lockup occurred. |
