Message-ID: <CAM-w4HPs=w3qZ8-zOFDUK+nrkdYq8A4gL0YdzhpCM2ELHiU=ww@mail.gmail.com> Date: Sat, 26 Mar 2016 18:59:39 +0000 From: Greg Stark <stark@....edu> To: linux-kernel@...r.kernel.org Subject: Continue to get freezes on Chromebook PIxel I continue to see freezes at random intervals on my Chromebook PIxel (2013). The X UI freezes completely for anywhere from a fraction of a second to several minutes but always eventually resumes. When it resumes there's normally nothing in dmesg or any other logs and no indication of exactly what exactly was happening when X was frozen. I had always chalked this up to the known problems with the intel graphics driver but apparently reports are that those problems are fixed and nobody else continues to see these freezes. I'm now suspecting that there's something else going on. Possibly the Sandisk iSSD apparently other Sandisk SSDs are buggy as hell so maybe the iSSD is as well? When the system returns there is usually a bunch of processes in disk wait including dm_crypt and usually several Chrome processes trying to page in stuff from swap. So blaming the SSD doesn't seem entirely out of line. On the other hand *anything* that locked up the PCI bus for a while would also cause lots of queued up I/O. I'm at a loss how to debug this. I'm looking for anything I can enable that would indicate what is blocking X and/or the kernel. Presumably there's some device driver waiting for some event for longer than is reasonable and either holding some kernel lock or hardware resource. Surely there are debug flags I can enable that will log whenever this happens so I can see after a freeze what was waiting on what for so long? I do have logs from a particularly long freeze where the kernel logged hung tasks. I suspect these just indicate what processes happened to be have wanted to do during the freeze that caused them to get stuck, not the culprit that actually caused them to get stuck. And I do have the intel driver debug flags enable but I think all this shows is that that the screensaver kicked in when the kernel finally unstuck and scheduled X: So please, if anyone has any suggestions of what tools to use or flags to enable to get visibility into what the kernel is doing when everything is frozen I would be more than happy to do further investigation on this end.
