I have tried a raid 0 configuration with the same equipment and get the same kernel panic. This error seems to happen under high load and/or large files. Running benchmark tests on smaller files 1-20 MB does not produce this error immediately. On my web page (http://people.redhat.com/dledford) there is a memory test script that will detect faulty RAM on a computer far better than any other test we've found to date. Can you please try this on your machine. The description given here, between the two different reports, more or less clears RAID5 (since one machine is RAID5 and the other RAID0) and our experience has been that these problems are almost always hardware related instead of RAID software related. The fact that both of you say you have N440BX based machines also makes it sound hardware related. You might want to check and see if ECC error correction is enabled in the BIOS on your motherboard (if you have ECC RAM, you might not). If you do have ECC RAM and ECC is enabled in the BIOS, then one of the best ways to see if you have RAM related problems is to check the event log in the BIOS and see if it reports any ECC errors. I have looked more closely into this problem and it looks likt the SCSI chipset on the N440BX board is not fully supported by RedHat 6.2. The SCSI controller is a "Symbios Logic 53C876 Dual Channel Ultra (one wide, one narrow)" and is listed as Tier 3 supported. Could this level of support be related to this problem? -eballweber This isn't a problem with raid, but with poorly supported hardware. |
