So I messed around with this machine for a good part of the day. I built and booted 3.14-rc4, then instrumented the mei and mei-me modules to show the various setup and teardown stages. I think they are correct. What I did find were some issues with MSI. In fact, if you boot with MSI disabled (pci=nomsi) on the kernel command line, then this machine won't _reboot_ without a power cycle. This seems indicative of a BIOS problem.
I then removed pci=nomsi and instrumented the MEI module such that it does not attempt to use MSI (instead uses normal threaded interrupts) and voila it started rebooting. I guess the solution is to either add a module parameter to the MEI module that allows one to selectively disable MSI, or get the platform BIOS vendors to fix their MSI support. Note that there are other consumers of MSI on this platform such as the igb NIC driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1154749 Title: reboot does a shutdown instead of rebooting (OCP v2) To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1154749/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
