From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.1) Gecko/20020827 Description of problem: When writing a large file to a reiserfs partition the load average climbs rapidly for the duration of the write, typically getting past 8 for a .5 gig file, and blocks any other IO tasks occuring on the machine. CPU loading remains minial according to top Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.dd if=/dev/zero of=/some/reiserfs/fs/temp count=1000000 2. 3. Actual Results: Load average climbs to typically 5-10 and io tasks get blocked Expected Results: On a stock kernel or on a redhat kernel writing to ext2 the load average climbs to approximately 1 and other IO tasks remain responsive. Additional info: The problem seems to occur with both kernel 2.4.9-31 and 2.4.18-17.7, but a stock 2.4.19 kernel appears to show the correct behavior, as does a debian box with a debian standard 2.4.18 kernel.
