This morning, the kernel went absolutely nuts on my Alienware M15x. It dumped literally millions of Emergency Thaw messages into syslog, many of which were malformed, like so:
bladernr@klaatu:~/Downloads$ grep "Emergency Thaw" /var/log/syslog |wc -l

Also, there are a lot of malformed stack traces... it's as though the kernel was dumping things to syslog faster than syslog could keep up, causing essentially a system wide denial of service and the various syslog messages were all munged together. They're so bad I can't really paste them here, so check out lines 581150-581201 from the syslog I've attached...
I have no idea what kicked this off, but it made the system unusable, forcing a reboot to clear it up. |
