Another thing to consider is that the IDE system seems to still be under development on the LKML. Earlier kernels tended to default rather conservatively. Newer more performance oriented boot time defaults may be setting some systems up for failure due to particular hard disk and motherboard chipset tradeoffs. People experiencing crashes and perhaps disk corruption might consider setting their hdparms values to less aggressive values. (NEVER set them more aggressively than the kernel defaults for given drives and chipsets.) This is a long shot to be sure. But if the crashes are really random and not related to specific applications then it may be a good idea to consider this potential. A journalling filesystem can mask the "corrupted filesystem" aspect of the usual IDE system defect. (You can thank some Open Source zealots for some of the state of the IDE system, today. They more or less drove off the fellow who was the chief asset Linux had for IDE development. I've seen maybe one post by Andre Hedrick in the last couple months.) {^_^} ----- Original Message ----- From: "Jack Bowling" <jbinpg@xxxxxxx> > You can turn off NPTL entirely systemwide by adding the following word > > sysinfo > > to the end of the kernel load line in your grub or lilo .conf.
