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.
