https://bugzilla.novell.com/show_bug.cgi?id=807726 https://bugzilla.novell.com/show_bug.cgi?id=807726#c0 Summary: Console loglevel (in kernel.printk) set too high after resuming from sleep or hibernation. Classification: openSUSE Product: openSUSE 12.2 Version: Final Platform: x86-64 OS/Version: openSUSE 12.2 Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: ivar_nikolaisen@hotmail.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Opera/9.80 (X11; Linux x86_64) Presto/2.12.388 Version/12.14 On a fresh reboot the loglevels are set as follows:

/sbin/sysctl kernel.printk kernel.printk = 1 4 1 7

But after resuming from sleep or hibernation it becomes:

/sbin/sysctl kernel.printk kernel.printk = 5 4 1 7

The console loglevel has gone from 1 to 5, meaning that after resuming lots of messages (in particular firewall events) get sent to the ttys (ctrl+alt+1,2,3 etc. terminals). This renders them almost useless since these messages are rather disruptive when working on the tty. Reproducible: Always Steps to Reproduce: 1. Boot computer 2. Check /sbin/sysctl kernel.printk 3. Sleep or hibernate 4. Resume system 5. Check /sbin/sysctl kernel.printk again. Actual Results: Console loglevel is set to 5 after resuming. Expected Results: Console loglevel should remain the same as on boot (1), or at least low enough that the ttys don't regularly receive firewall events. I have verified that the problem is present on both openSUSE 12.2 and 12.3 RC2 (all my installs are x86-64). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=807726 https://bugzilla.novell.com/show_bug.cgi?id=807726#c2 Takashi Iwai changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tiwai@suse.com --- Comment #2 from Takashi Iwai 2013-10-16 10:16:09 UTC --- It must be some leftover bug while transition to systemd. pm-utils has a hook in sleep.d/00logging where changes the kernel loglevel upon suspend/resume. It saves the previous state before suspend in /var/run/pm-suspend file. In the past, this file was evaluated via pm-utils/functions, and the saved value was restored at resume. But this eval was lost via systemd move, thus $KERNEL_LOGLEVEL is empty when the hook is executed. A quick fix would be to rewrite 00logging script to save and restore the value using its own /var/run/* file. BTW, I checked a laptop with fresh 13.1-rc1 installation, and the problem still exists (tested on XFCE). I wonder why no one actually didn't care... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=807726 https://bugzilla.novell.com/show_bug.cgi?id=807726#c5 --- Comment #5 from Lee Duncan 2013-10-21 14:06:55 PDT --- Interesting ... It looks like /usr/lib/pm-utils/sleep.d/00logging already creates a state file when suspending or hibernating: case "$1" in hibernate|suspend) [ -n "$PM_LOGFILE" ] || exit 0 # save the old loglevel read KERNEL_LOGLEVEL DUMMY < /proc/sys/kernel/printk echo "export KERNEL_LOGLEVEL=$KERNEL_LOGLEVEL" >> /var/run/pm-suspend # set the loglevel so we see the progress bar. # if the level is higher than needed, we leave it alone. if [ $KERNEL_LOGLEVEL -lt 5 ]; then echo 5 > /proc/sys/kernel/printk fi ... So all I should have to do is read from it, if present. I will attach a suggested patch, which seems to work for me. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Please test on your system, where files are located in /usr/lib/pm-utils/sleep.d. Be sure to remove old 00logging file from directory, once backed up and patched, since the "resume" logic runs all files in the directory. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I added your patch to develproject. Should I make a maintenance request for 12.2/12.3?

Based on the low risk of the fix and the severity of the problem, I would say yes, please submit to both. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
