Hi everybody, I just tried mainline Linux 4.1-rc8 on my Bananapi. Even though my configuration[1] is essentially the same as used for Linux 4.0.5 (which runs fine), I now see lots of messages about clocksource htimer in syslog or even on the screen (using simple framebuffer). The messages look like this:
Jun 20 04:32:59 BPI kernel: [ 7.536524] clocksource hstimer: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 21718868714 ns I never saw these on 4.0. The messages seem to be related to frequency changes of the CPU. If I set the scaling governor to performance, the messages go away (there are still some during but not anymore after the system is up). I don't seem to be the only person with this issue. If you search for the message, you will find a couple of persons with them, mostly on Cubietruck. Does anyone else from the sunxi community see these message? Or does anybody here know why they are coming up? Is there a fix for this? Btw. I use U-Boot 2015.04. I suppose that should work, but let me know if that might be an issue or a newer U-Boot might help. I also found this issue[3] on github with the same message: But CONFIG_GENERIC_CLOCKEVENTS is already enabled in my case. So I'm stuck. Please let me know if you need more information to narrow down the issue.
