Summary: pdflush uses 5% CPU on otherwise idle system
Product: IO/Storage
Version: 2.5
Kernel Version: 2.6.30
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Block Layer
AssignedTo: axboe at kernel.dk
ReportedBy: pm at debian.org
Regression: Yes
The second pdflush process is the top process in "top" output, varying between
3% and 6% CPU, even when no file system activity is happening, and this remains
true after a forced "sync".
This is a regression from 2.6.29.
