Comment 1 Ben Collins 2003-10-29 09:24:09 UTC 
This is fixed in the SVN tree, is known and will be merged to 2.6 after 2.6.0 is
released.
Comment 2 Adrian Bunk 2004-07-17 17:45:59 UTC 
According to the comment of Ben, it should already have been fixed in recent 2.6
kernels.

Please report if this isn't true.
