Using the new code in NetBSD, I get a “panic: pdti 206067” in pmap_enter(). What should I do?
Increase NKPDE in /sys/i386/include/pmap.h. The largest it should be 31; see question 3.2.8.1 for other useful values. Be sure to keep the changes around as a patch file, since this is one of the files that will get overwritten during a source code update. Note that in the versions of NetBSD newer than 1.2.1, this value is computed, so you won’t need to change it. 2.4.3a : I get the error “isr 15 and error: isr 17” on an NE2000 card. 2.4.3b : I have some card on IRQ2 and it doesn’t work; why? 2.4.3c : I am getting lousy performance out of my network card. What are some of the other possibilities? The description of this problem is that one of the cards in your system (most likely the VGA card) is either generating interrupts or is causing the IRQ 2 to be actively disabled. Older VGA card used IRQ 2 during vertical retrace to prevent sparklies. One solution would be to plan on not using your Ethernet card (or any other card you want on IRQ 2) until you have rebuilt the kernel so that it
