Bug ID: 188331
Summary: ACPI AE_NOT_FOUND errors aggressively being spawned,
filling up log files.
Product: ACPI
Version: 2.5
Kernel Version: 4.4.0-47-generic
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Other
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Here's a small sample of the errors: http://pastebin.com/b2Jv8z37
While these errors definitely have a purpose, these error messages are created
far too quickly, and this causes severe problems on my system at least, the
logs become bloated with these messages, completely filling my root partition,
preventing me from using my system. I believe that anyone else who is able to
trigger these messages at such a high rate will have the same problem.
Based on the amount of messages and the time given for each, it appears that
this error message appears approximately 1000 times per second (on my system),
creating 3000 lines per second or ~400000 bytes per second (on my system). This
fills up about 1.4 GB per hour (on my system) which fills up my root partition
in less than a day. Once my root partition is filled, my system becomes
unusable.
My preferred solution to this issue is to limit the rate at which these
messages appear. A limit of one error message per second seems like a good
idea.
