https://bugzilla.novell.com/show_bug.cgi?id=750106 https://bugzilla.novell.com/show_bug.cgi?id=750106#c0 Summary: Recent system update results in 'Error inserting lirc_serial : Device or resource busy' and kernel panic. Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: openSUSE 12.1 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: vodicka.petr@email.cz QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=479148) --> (http://bugzilla.novell.com/attachment.cgi?id=479148) Kernel trace logged few seconds before kernel panic. User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:10.0.2) Gecko/20100101 Firefox/10.0.2 Yesterday I have updated my PC, which I am using as HTPC (last update I made about 14 days ago and no problem till yesterday). During reboot mesage "Error inserting lirc_serial (/lib/modules/3.1.9-1.4-default/kernel/drivers/staging/lirc/lirc_serial.ko): Device or resource busy" appeared and few seconds later kernel trace showed up and after few more seconds kernel panic occured. I tried to reboot many times when searching for workaround and I managed to boot without these errors in about 1 of 10 tries (maybe some race condition???). I tried to downgrade to 3.1.0 kernel from oss repository and same error appeared after reboot so problem must be somewhere else. I tried default and desktop kernels too. Finally I founded a workaroud. Only runlevel 1 was working, so I had to disable loading of module lirc_serial during boot (deleted lirc_serial from /etc/sysconfig/lirc file) and then after succesfull boot to runlevel 5 I had to load module manually "modprobe lirc_serial" with no errors. After that everything is working, PC is running rock stable. But I have to load module manually after every reboot. Reproducible: Always Steps to Reproduce: 1. Make update of system. 2. Enable lirc_serial module loading in /etc/sysconfig/lirc file. 3. Reboot. Actual Results: Kernel panic. Expected Results: Normal boot.

But I tried to downgrade to "12.1 without updates" and I compared kernel logs. Working older version: vodic-server kernel: [ 56.378103] lirc_serial: module is from the staging directory, the quality is unknown, you have been warned. vodic-server kernel: [ 57.284099] lirc_serial: auto-detected active low receiver vodic-server kernel: [ 57.285171] lirc_serial lirc_serial.0: lirc_dev: driver lirc_serial registered at minor = 0 vodic-server lircd-0.8.7[2372]: lircd(default) ready, using /var/run/lirc/lircd Recent not working version: vodic-server kernel: [ 34.661786] lirc_serial: module is from the staging directory, the quality is unknown, you have been warned. vodic-server kernel: [ 34.672573] lirc_serial: port 03f8 already in use vodic-server kernel: [ 34.677725] lirc_serial: use 'setserial /dev/ttySX uart none' vodic-server kernel: [ 34.677730] lirc_serial: or compile the serial port driver as module and vodic-server kernel: [ 34.677734] lirc_serial: make sure this module is loaded first So it looks that problem is that lirc_module is loaded almost 20 seconds earlier and before bool.local where "setserial /dev/ttyS0 uart none" command is located. I also realized that kernel panic occured on setserial command (not in log, only on screen and it was always out of screen so I didn't see that). To make sure I disabled again loading of kernel module in /etc/sysconfig/lirc and added line "modprobe lirc_serial" to /etc/rc.d/boot.local after "setserial /dev/ttyS0 uart none" line and it worked. But I don't know how to repair that "clean way". Probably setserial command should be in /etc/rc.d/lirc, but if I write it there, it will be overwritten after update. Or make lirc_serial module to be loaded before serial module (it should work without setserial command), but I don't know how to do that, so I didn't test this solution. -- 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.

When setserial is called later than lirc_serial module load, lirc is logging that serial port is occupied (and not working after boot), but system is booting normally. Only difficulty is that lirc_serial module can't be set in /etc/sysconfig/lirc where it logically belongs. Maybe subject for improvement in new version :) -- 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 didn't know about this file, but it looks as the right place. Than lirc_serial could be defined in /etc/sysconfig/lirc file. I will test this today. -- 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.

It is called too early :) I also tried add "pre-install lirc_serial setserial /dev/ttyS0 uart none" to /etc/modprobe.d/lirc file, but it's the Gentoo way which is not working in OpenSUSE. So only working, but not clean way, is to add lines "modprobe lirc_serial" and "setserial /dev/ttyS0 uart none" to boot.local and remove lirc_serial from /etc/sysconfig/lirc. -- 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.
