** Description changed: 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 16134519 Apr 17 11:40:05 klaatu kernel: [87482.066719] Emergency Thaw on sda6 Apr 17 11:40:05 klaatu kernel: [87482.066722] Emergency Thaw on sda6 Apr 17 11:40:05 klaatu kernel: [87482.066725] Emergency Thaw on sda6 Apr 17 11:40:05 klaatu kernel: [87482.066729] Emergenaw on sda6 Apr 17 11:40:05 klaatu kernel: aw on sda6 Apr 17 11:40:05 klaatu kernel: [8748aw on sda6 Apr 17 11:40:05 klaatu kernel: <aw on sda6 Apr 17 11:40:05 klaatu kernel: aw on sda6 Apr 17 11:40:05 klaatu kernel: [aw on sdaaw on sda6aw on sda6 Apr 17 11:40:05 klaatu kernel: <aw on sda6 Apr 17 11:40:05 klaatu kernel: <4aw on aw on sda6 Apr 17 11:40:05 klaatu kernel: <4aw on sda6 Apr 17 11:40:05 klaatu kernel: aw on sda6 Apr 17 11:40:05 klaatu kernel: [87482.aw on sda6 Apr 17 11:40:05 klaatu kernel: aw on sda6 Apr 17 11:40:05 klaatu kernel: aw on sda6 Apr 17 11:40:05 klaatu kernel: <aw on sda6 Apr 17 11:40:05 klaatu kernel: last message repeated 2 times Apr 17 11:40:05 klaatu kernel: [87482.066793] Emergency Thaw on sda6 Apr 17 11:40:05 klaatu kernel: [87482.066796] Emergency Thaw on sda6 Apr 17 11:40:05 klaatu kernel: [87482.066800] Emergency Thaw on sda6 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.
