This is a package on Manjaro Linux with the description: Linux Advanced Power Management source code here: https://github.com/linrunner/TLP I'm using it to set my devices to 'auto' mode, and supposedly save power By "without tlp" above I meant that I made sure tlp didn't set any device into low power mode or anything like that. > >> "auto".

So, apparently something(?) is turning off something(as in power off/suspend?), so that the poweroff functionality from kernel is currently unable to flush drive cache or put drive into standby mode during the poweroff which it needs to do. So whatever that is, is probably the one that's doing this "HC died" thing too. So I don't think I should worry, as you said anyways. > > Furthermore, the lsusb output says you don't have any USB devices > plugged into either of the OHCI controllers.

I have worked around the shutdown issue that was preventing my SSD from gracefully shutdown and this USB issue seems to not affect me anyways. (details here btw: https://bugzilla.kernel.org/show_bug.cgi?id=151631 ) Thanks and sorry for the spam. But if I can do anything to help with testing patches or anything regarding usb issue(s) I'd be happy to. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
