I have added some new code to the TCP/IP stack of a FreeBSD 3.2, and now I'm trying to create a new kernel which would include the upgrades added. I follow the "config, make depend, make, make install" sequence as specified in Chapter 7 in your freebsd.org handbook, and everything seems to turn out right. Now, the problem is that, after the reboot phase (and entering "login" & "password"), the new kernel seems to work right (i.e., for a while, all the commands work ("ls", "ping", "ftp", "ps", etc)), but after one or two minutes, it hangs. Then, the following message appears on my screen: _____________________________________________________________________________ panic: m_copym syncing disks... Fatal trap 12: page fault while in kernel mode fault virtual address = 0xb8 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01625cf stack pointer = 0x10:0xc02cf060 frame pointer = 0x10:0xc02cf060 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL0, pres 1, def32 1, gran 1 processor flags = interrupt enabled, resume, IOPL = 0 current process = Idle interrupt mask = bio trap number = 12 panic: page fault Automatic reboot in 15 seconds... press a key on the console to abort _______________________________________________________________________________ Do you have any idea about which could be the problem or how could I solve it? Thank you very much, Carles Gómez Montenegro Polytechnic University of Catalonia PD: previous to this process, I built a new kernel (without any upgrade, just to test the bulding sequence) and everything worked, so I think it's me who's the reason of the problem...
