Going further, I've found that just doing 'set hw.apic.mixed_mode=0' at the boot loader without changing any other settings also prevents the lockups. Based on this, I have a few more questions. The biggest one is is there anything else that can be done to further narrow down the cause? I've read the blurb in src/sys/i386/conf/NOTES, and it suggests that the kernel is possibly getting incorrect information (i.e. enabling mixed mode when it shouldn't). Is there a straightforward way to determine what information the kernel is using? Is it necessairly a bad thing that mixed mode has to be disabled?Received on Fri May 14 2004 - 15:24:16 UTC
