It still hangs at boot time with a card in it even with the above (diff.4 actually) applied and the sysctl is set. More news. It always hangs at the same place, no matter which slot the card is in. It hangs right here: FreeBSD 4.4-RC #0: Fri Aug 17 10:06:50 MDT 2001 nate@caddis.yogotech.com:/usr/src/sys/compile/CADDIS Timecounter "i8254" frequency 1193182 Hz CPU: Pentium III/Pentium III Xeon/Celeron (796.54-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x68a Stepping = 10 Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE> real memory = 134152192 (131008K bytes) avail memory = 127049728 (124072K bytes) Preloaded elf kernel "kernel" at 0xc0384000.

Now it got past the pcic* bootlines for some reason (first time ever, using the same kernel it hung on before), and the last line printed out was 'pcic0: Event mask 0xf'. This was a warm reboot after having no cards in, so maybe that had something to do with it. (I have the patch in place, but I haven't disabled the pcibios per the sysctl.) Rebooted again, and now it actually came up, and saw my modem. This is getting weirder and weirder all the time. Not, when I eject the modem (which works), I get: pcic0: Event mask 0xc pcic0: debounced state is 0x30000186 And it ejects! However, no joy on re-insertion. It appears there's some sort of race that got won this time at bootup, and once it's up, it lost the race. :( Rebooting the box again caused the normal 'boot' hang described above. However, this time I had to do a cold reboot, since the box was hung. But, if I do a warm reboot (inserting the card *after* FreeBSD has rebooted, but before is tarts booting again), it'll get a bit further and either go all the way or die with the pcic0: Event mask 0xf. (I'm not sure what's the trigger for getting further) Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
