Today, I ran "yum update" on the "other Fedora 8" machine mentioned below. After rebooting with the new kernel (2.6.25.9-40.fc8) I'm seeing the application failures due to intermittently missing files. After rebooting with the old kernel (2.6.23.15-137.fc8) the machine is completely stable again. I'd say it is pretty clear there is a bug in the newer kernels. For the records, the first kernel version I know is broken is 2.6.25.4-10.fc8. ----- Original Message ---- From: Ralf W.

When immediately trying again the exact same command it (usually) works. We see this behavior on three systems: Fedora 8: 2.6.25.4-10.fc8 #1 SMP Thu May 22 22:58:37 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux Fedora 8: 2.6.25.6-27.fc8 #1 SMP Fri Jun 13 16:17:54 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux Fedora 9: 2.6.25.9-76.fc9.x86_64 #1 SMP Fri Jun 27 15:58:30 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux We have other Fedora 8 systems with older kernels that are completely stable, e.g.: 2.6.23.15-137.fc8 #1 SMP Sun Feb 10 17:03:13 EST 2008 x86_64 x86_64 x86_64 GNU/Linux We had intermittently missing files on both local disks (ext3) and over NFS, with mounts form various hosts including a Netapp filer that's serving 30+ other machines without a problem. My best way of demonstrating the problem is to repeatedly run SCons (which is a make replacement) on a large source tree with several thousand files. This performs a full dependency analysis and should just find that everything is already up-to-date. About 10% of the SCons runs fail with "missing" file warnings, or spurious recompilation, presumably because header files are intermittently missing, which changes the source signatures. I already asked the SCons people, the hardware vendor, 3ware support, and I ran yum update a few times in hopes that the problem goes way. So far it has been persistent. Has anybody on this list seen similar problems?
