I still have to work with hardware that requires ata_dma disabled. It seems to be required for most systems I've worked with that have a compact flash socket on the mainboard (sometimes you can just limit the mode to udma33 or less, sometimes you have to turn it off completely.) Adding kern.eventtimer.periodic=1 seems like a good idea. As a general philosophical thing, I don't have a problem with the idea "safe mode turns off everything that has ever historically been problematic," because I don't think anyone expects a system to run well in safe mode. I see it more as a tool to start narrowing down the area of trouble, like step 1 of a binary search for the problem. As such, the most important aspect is a comprehensive list of what changes for safe mode, so that you can procede by selectively en/disabling the various things it does. -- Ian _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
