I've tried to attach a "boot -v" too. I too have a panic. In my case the panic happens when we construct the init(8) process and in particular when we write the very first by out to the stack. There's a page fault for it, which is expected, but when we try to handle the page fault in the IVT something happens the moment we switch to physical addressing. The end result is that we dont call trap with vector 0x14 (i.e. a page fault), but with vector 0x18 (general exception). The kernel doesn't know what to do with that and panics. Your panic looks different, but if you could put a breakpoint on subyte()+0x41. The st1 instruction writes to user space. Can you check if the machine reboots because of that instruction? If yes, we may be looking at the same problem. We just have different failure modes then. If you don't even reach subyte() then I assume you're having a different problem. > uhub0: port 1, set config at addr 2 failed > uhub0: device problem (INVAL), disabling port 1 > uhub0: port 3, set config at addr 2 failed > uhub0: device problem (INVAL), disabling port 3 I see ukbd and ums devices at this point. > Timecounters tick every 1.000 msec > md0: Preloaded image </boot/mfsroot> 8388608 bytes at > 0xe000000004c13118 I'm netbooting and have root over NFS. I'll try the snapshot myself and see if I have the same failure. ... > pcib0: matched entry for 0.2.INTB > pcib0: slot 2 INTB hardwired to IRQ 18 > Loading.: HP-UX Primary Boot: 0/1/1/0.0.0.0.0 > Starting: HP-UX Primary Boot: 0/1/1/0.0.0.0.0 This is weird.... I seem to recall having problems with verbose boot as well. It may be a compiler bug... FYI, -- Marcel Moolenaar xcllnt@mac.com
