Can anyone tell me if there has been testing of using an SMP kernel on a UP machine and if that is bad? I have an ext3 filesystem that keeps getting corrupt. Certain directories only get I/O errors, trying to access beyond the end of the device. Thanks, Gabe

I figured I would add some information. The drive is an external, scsi attached IDE drive raid enclosure. I have an aic7xxx scsi card, 2.4.16-xfs-ext3-smp kernel.

Are there any known problems with 2.4.16? On 2/8/02 11:28 AM, "Stephen C. Tweedie" <sct@redhat.com> wrote:> Hi, > > On Fri, Feb 08, 2002 at 11:18:10AM -0800, Gabe E.

She will be getting another one soon, and in anticipation of that I compiled SMP into her kernel. It works fine; it has not crashed once in the two months she has been using it. -- -- Skylar Thompson (skylar@attglobal.net)
