It is currently running RH 8.0 kernel 2.4.18-27, but the problem has been present at previous versions. I suspect a hardware issue of some kind, since most of our systems are running this software, but am not getting any error messages. I've installed the debug kernel, and using kdb alt-sysreq-p have determined that all of the tasks get hung up in "jbd:do_get_write_access". Basic scheduling is still working, but anything that attempts to access the disk hangs. Are there any other steps I can take to debug? I've run basic hard disk read diagnostics and not found any problems, as well as memtst86. Thank you, Orion Poplawski
