kernel config
I've been running for at least a week (I think more like a month) with no issues with suspend. doesn't pm-suspend just call some kernel thing, not do anything itself? Does it work with 3.10.10? (since you said it failed with 3.10.11) No, it did not. I also tried .3, .4, .7, as i remember non of them worked, but i am not entirely sure. pm-suspend does a lot things: # ls /usr/lib64/pm-utils/sleep.d/ 00logging 00powersave 01grub 49bluetooth 75modules 90clock 94cpufreq 95led 98video-quirk-db-handler 99video Ok, just making sure. Can you try with a vanilla kernel? sys-kernel/vanilla-sources-3.11.1 works fine, does not hang when pm-suspend is used. Ok, hardened kernel with grsec/pax disabled? With 'CONFIG_GRKERNSEC is not set' 3.11.1-hardened works fine. So no you know what to do :P Differential analysis (enable some stuff and see what happens).

I'ver removed 3.10.10 and 3.10.11 from the tree. (In reply to Nikoli from comment #3) > No, it did not. I also tried .3, .4, .7, as i remember non of them worked, > but i am not entirely sure.

Why? I see no info that this is a regression over 3.10.1-r1. Hm, i don't see the reason to remove those versions. I for myself run hardened kernels on my servers (most people do?), where nobody cares about suspending and actually i didn't want to move to 3.11 until it becomes a bit more mature. Since the 3.10 is a LTS, is it possible to reintroduce the 3.10.x in the tree? I don't think that grsecurity (our upstream) will support 3.10 as an LTS. (In reply to Matthew Thode ( prometheanfire ) from comment #14) > I don't think that grsecurity (our upstream) will support 3.10 as an LTS. actually you don't need to think, they won't. they've already moved on to 3.11. Can the reporter test against 3.11.1-r2. 3.11.1-r2 still hangs. (In reply to Nikoli from comment #17) > 3.11.1-r2 still hangs. can you reproduce it when X is not running? Tried doing '/etc/init.d/xdm stop' before pm-suspend, nothing changed, still hangs. Kernel was 3.11.1-hardened-r2. (In reply to Nikoli from comment #19) > Tried doing '/etc/init.d/xdm stop' before pm-suspend, nothing changed, still > hangs. Kernel was 3.11.1-hardened-r2. that is, you issued suspend from a normal text console? weird, 'cos that works for me here. now the question is whether you could do what Matthew said in comment 9: a binary search for the config option that triggers the problem then we have something to go on and figure out what the cause is. you can take your time 'cos i won't have net access for a while anyway.

Well, for the test version at least. According to https://grsecurity.net/ their stable patches still address the 2.6.32.* and 3.2.* longterm versions of the Linux Kernel, so maybe there is hope? Of course it were a bit sad if they decided not to support 3.10. It would keep many wondering about what will be the next longterm supported by grsecurity, especially since longterm releases appear to be becoming rare. 3.11.6-hardened-r1 seems to work fine :) ok, marking fixed then, if not fixed, bug us :D |
Created attachment 358812 [details] dmesg /usr/sbin/pm-suspend worked fine until update to kernel 3.10, now it is broken with 3.10.11 and 3.11.1 hardened kernels, with kernel 3.9.9 it works fine. 'echo mem > /sys/power/state' works fine for 3.11.1-hardened kernel. When using pm-utils for suspend to RAM with latest hardened kernel system goes to sleep fine as usual, but after wakeup it works fine only several seconds, then cursor in KDE-4.10.5 session stops moving and no reaction to input devices or network happens. Attached kernel messages before hang. Not sure if it is kernel or pm-utils bug.
