In each case, the system appears to die when writing a large file (the text of "The Complete FreeBSD", about 40 MB). This isn't surprising, I suppose. Dumps and debug kernel are available, but don't show me much. I'm still researching this one, but if the following list of changes catches anybody's eyes, I'd be interested in hearing from you. First, the changes: Old New P54C, 133 MHz K6/233 Old motherboard, IWill P55XB2, Intel TX chipset forgot the name 96 MB SIMM memory 128 MB mixed EDO SIMM and SDRAM Adaptec 1542A and Adaptec 2940UW and 2940 host adapters 2940 host adapters IDE system disk IDE system disk I've checked all sorts of things, including: changing the CPU back (still panics) playing around with the host adapters (inconclusive). It looked as if the 2940UW might have been the culprit, since I was writing on a disk on that adapter, but once it corrupted the IDE /usr, and after swapping around to put /home on the 2940, it still failed. upgrading from last week's -current to today's -current. No change. Any ideas? Greg
