I am able to reliably crash ac13 on my ABIT bp6 dual celeron machine. The procedure I used is the following: boot machine login as root umount /dev/hde1 fsck -f /dev/hde1 The fsck completes around 5-10% before causing a kernel panic. /dev/hde1 is mounted on /usr/src and is not used for any critical resources. The hde1 interface uses the HPT366 IDE interface, while the root directory (/dev/hda) uses the Intel chipset. DMA is enabled at boot; no manual hdparm modifications have been made. I am including as attachments: IDE bootup messages ksymoops output (from hand-copied kernel OOPS) lspci /proc/cpuinfo /proc/modules /proc/version -Kevin -- ------------------------------------------------------------------------ | Kevin O'Connor "BTW, IMHO we need a FAQ for | | koconnor@cse.buffalo.edu 'IMHO', 'FAQ', 'BTW', etc. !" | ------------------------------------------------------------------------
