Public bug reported: This occurs only if you have a USB interface.
Whenever I've installed a new kernel (through updates only), something called evbug.c appears prevalently, and pretty much every picosecond that the system is up. Here's what it looks like. [ 177.005744] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 0, Code: 0, Value: 0 [ 177.017835] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 3, Code: 24, Value: 0 [ 177.017841] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 3, Code: 28, Value: 0 [ 177.017845] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 1, Code: 333, Value: 0 [ 177.017849] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 0, Code: 0, Value: 0 [ 177.031187] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 0, Code: 0, Value: 0 [ 177.041000] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 0, Code: 0, Value: 0 [ 177.055526] evbug.c: Event. Dev: isa0060/serio1/input0, Type: 0, Code: 0, Value: 0 ------ Obviously truncated for various reasons. I took a look at the logs (after unplugging my USB mouse), and noticed that it occurs roughly 249 times a second. In the seven seconds alone that I let this run, the log (using dmesg | grep -i evbug > evbug.txt) had become 123.2KB. *All* of that size is from *only* that message! For me, this has caused my log files to swell to enormous sizes, before I knew a workaround existed. By the time I found it, my log file was about 3GB, and I had no other choice than to write what was in there to /dev/null. Anyway, this is is a serious bug, which many people need to be made aware of, and it needs to be fixed immediately. Here's the workaround I used from http://linux.derkeiler.com/Mailing- Lists/Debian/2004-01/5537.html : 1) sudo rmmod evbug 2) sudo rm /lib/modules/$(uname -r)/kernel/drivers/input/evbug.ko ...and the messages stop, until I install another kernel. If I get the time, I can write an [ugly] patch in the form of a cron job that will check to see if evbug.ko exists, and then perform the commands. ** Affects: ubuntu Importance: Undecided Status: New -- evbug.c spams logs and causes high system loads https://bugs.launchpad.net/bugs/240553 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
