Hi Christopher, 1) I tried removing iwlwifi and iwlmvm and then suspending. In both kernel 4.20.3 and 5.0.0-rc2 the result was the same.
I tried just leaving the system to run *without suspending*, and I found that the system would lock up after a few minutes anyway. The memory steadily increased (but nowhere near full) and the system load hit 5 (out of 4 CPUs). In both cases jbd2 was consuming 100% CPU at the time it locked up. I would normally think this was a disk issue in this case but I can't replicate it on Ubuntu kernel 4.18 (and I use this machine all day every day) so I don't think the issue is faulty hardware. 2) On a short suspend/resume cycle (before the system locked up) I resumed and reenabled the module. This time Network Manager appeared to connect, however the system locked up very shortly after that. I think there is a deeper issue here. Perhaps with jbd2 or kworker. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1472832 Title: Suspend issue with Dell Venue 11 Pro 7140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1472832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
