Hi, I have just managed to repetedly panic -CURRENT... How you ask? I'll tell you :-D The short story is "Run a linux version of XFree86," here's the long story: first, I got the linux version of XFree86, along with all it's driver modules (compliled under linux of course). Then in /usr/compat/linux/dev, I created tty entries using mknod (mknod tty0 c 12 0, etc.. for each tty up to 5) then I did this: /usr/compat/linux/usr/X11R6/bin/XFree86 the XFree86 said "error switching terminal's" or something similar, and immediately after that, FreeBSD panics with the following: Fatal trap 12 while in kernel mode fault virtual address = 0x4 fault code = supervisor read, page not present instruction pointer = 0x8: 0xc0204f57 stack pointer = 0x10:0xf94dfaf8 frame pointer = 0x10:0xf94dfb14 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 262 (XFree86) kernel: type 12 trap, code = 0 I didn't write all the argument adresses down because my computer was stuck beeping at me... just one constant beeeeeeep until I restart the computer so I wanted to reboot it as fast as possible, if these are needed, I can go back and get them. They all appeared valid anyway (none of them were NULL) db> trace scioctl + 0xa33 spec_ioctl + 0x26 ufs_vnoperatespec + 0x15 vn_ioctl + 0x10f ioctl + 0x288 linux_ioctl_console + 0x209 linux_ioctl + 0x54 That's basically the end, there was more but I think this is all that's relevant... Anyway, If anyone reproduces this or fixes this or even reads this and has more questions, please let me know. Thanks.
