Is there a "harmless" but user-visible magic command I could practice this with (during normal operation), so I can find out how to do a REISUB next time? Lastly, a bit of a btw, I've never managed to execute an Alt-Sysrq-REISUB to force a cleaner shutdown, but that's probably because I'm on a laptop, PrintScr is only accessible via an Fn key, and I'm not sure of the exact key sequence I need. in kern.log: ? How do I get this human-readable? I imagine I could pinpoint the time it happens via log timestamps, but how do I read timestamps like e.g. Which log files can tell me what's going wrong? More or less blindly searching in the sys log viewer reminds me of needles in a haystack. How do I diagnose that? It does not happen on every shutdown, but often enough to be annoying (as it forces a diskcheck on reboot, of course). Only resolution is hard power-off (holding power key for several seconds) - neither Ctrl-Alt-Backspace (which normally works, I have it switched on in Settings) nor Ctrl-Alt-Del help, nor can I get into a text console with Ctrl-Alt-F1. I feel it happens near the end of a normal shutdown cycle, judging from time elapsed. There's just a black screen, no harddisk activity, it justs sits there. It is another thing to successfully load a Linux Kernel.Įxperimentally, I might try moving away from Ubuntu and its derivatives.Since one or two months ago, my laptop with ubuntu 12.10圆4 hangs during shutdown. It is not enough for them to check the laptop with Microsoft Windows and declare it alright now. You should describe your difficulty to them and ask them for a solution. I would take this up with the manufacturers again. Your first post in this thread says " platform idma64.0: failed to claim resource 0: " I assume this was after the laptop was returned and "mended" by the manufacturer. It says "There's a kernel bug opened about this, indicating the problem might be in the machine bios, if you are seeing a "failed to claim resource" message in your kernel log - " RTL8411B PCI Express Card Reader (rev Clevo Initial Series NL51LU is described as a Linux computer with a variety of distros being possible.
