Comment 24 for bug 157777

Since upgrading my ancient Gateway 6400 server to Ubuntu 7.10 (Gutsy), the system has experienced a number of random lockups. I have been working on trying to resolve the problem for a solid week with limited success.

My Gateway 6400 server hardware is as follows:

    * 2x 1GHz Intel Pentium III (Coppermine) CPUs
    * 1GB ECC memory
    * 1x LITEON LTN301 ATAPI IDE CD-ROM
    * 1x Python 06240-XXX 8160 DAT Drive
    * 4x IBM DPSS-318350N Fast Wide SCSI Drives (ServerWorks SCSI Controller)
    * Intel(R) PRO/100 NIC
    * RealTek RTL8139 NIC
    * Generic embedded VGA display

My system is NOT running an Xserver. I re-installed the old 2.6.20-16 kernel that shipped with 7.04 (Feisty). Since then, I have experienced 10 days uptime without a single glitch! I believe that I can confirm this as a kernel issue. Something has changed since the 2.6.20 kernel that causes hard locks on my server. My system logs have not shown a single error and Magic SysRq does not work for a safe re-boot. I also tried a newer 2.6.23-8 kernel and was no better than the 2.6.22-14 kernel that shipped with Gutsy.
