Subject: 2.6.2-mm1 problem with umounting reiserfs
Date: Fri, 06 Feb 2004 15:02:25 -0700 [thread overview]
Message-ID: <1076104945.1793.12.camel@spc.esa.lanl.gov> (raw)
With kernel 2.6.2-mm1, I got the following when umounting a reiserfs
file system. I did not get this with 2.6.2-rc2-mm1 or stock kernel.
Base distro is Mandrake 10.0 beta2. System is UP PIII.
