The errata for 5.2 mentions: (10 Jan 2004) Although APIC interrupt routing seems to work correctly on many systems, on some others (such as some laptops) it can cause various errors, such as ata(4) errors or hangs when starting or exiting X11. For these situations, it may be advisable to disable APIC routing, using the ``safe mode'' of the bootloader or the hint.apic.0.disabled loader tunable. Note that disabling APIC is not compatible with SMP systems. I followed the directions and got rid of my watchdog timeout problems. Unfortunately, either XFree86 in 5.2 is broken somehow (and nvidia's drivers don't work anymore) or this affects XFree86 (and then that breaks nvidia's drivers). Since somehow nvidia's drivers were broken and couldn't go above 8bpp and neither could X's nv driver, so I want back to 5.1 > Is there something I can do to help solve the problem? >From what I see, nope. For you, it looks like you can't disable APIC, since you have a SMP system. And that's assuming your problem is the same sort of problem mine is anyhow. -- Robin Schoonover (aka End) # # "355/113 -- Not the famous irrational number PI, but an incredible # simulation!"
