[Bug 900811] New: iwlmvm and mac80211 crash randomly - only reboot helps

http://bugzilla.opensuse.org/show_bug.cgi?id=900811 Bug ID: 900811 Summary: iwlmvm and mac80211 crash randomly - only reboot helps Classification: openSUSE Product: openSUSE 13.1 Version: Final Hardware: x86-64 OS: openSUSE 13.1 Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: srinidhi@novell.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 609747 --> http://bugzilla.opensuse.org/attachment.cgi?id=609747&action=edit Snippet from /var/log/messages iwlmvm and mac80211 kernel modules crash almost randomly. I haven't managed to figure out what causes these crashes. I'll try to provide as much information as I can. Please let me know if you need any additional information. I'll paste syslog as attachment. After the crash, syslog is flooded with the last line mentioned in the attachment. I've tried running:

# modprobe -r mac80211 cfg80211 iwlmvm iwlwifi # modprobe iwlwifi

But nothing helps. Only a reboot allows wireless connectivity. Additional information:
