I think so; I've followed http://www.daemonology.net/blog/2009-07-11-freebsd-update-to-8.0-beta1.html and ran "freebsd-update -r 8.0-RC1 upgrade", "freebsd-update install", rebooted, reran "freebsd-update install", rebooted and ran ndisgen. > And you really did loaded regenerated module? Yes, I ran ndisgen and used kldload to load the generated module and besides I copied the module to /boot/modules and tried loading it after the kernel panics. >> >> I'll paste some sections from core.txt; I can attach the whole file if you >> want. >> >> ----------- >> >> Unread portion of the kernel message buffer: >> >> >> Fatal trap 12: page fault while in kernel mode >> cpuid = 0; apic id = 00 >> fault virtual address = 0xc4ea831a >> fault code = supervisor read, page not present >> instruction pointer = 0x20:0xc4df96b3 >> stack pointer = 0x28:0xe3744a44 >> frame pointer = 0x28:0xe3744aac >> 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 = 1110 (ifconfig) >> trap number = 12 >> panic: page fault >> cpuid = 0 >> Uptime: 36s >> Physical memory: 883 MB >> Dumping 67 MB: 52 36 20 4 >> >> Reading symbols from /boot/kernel/snd_hda.ko...Reading symbols from >> /boot/kernel/snd_hda.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/snd_hda.ko >> Reading symbols from /boot/kernel/sound.ko...Reading symbols from >> /boot/kernel/sound.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/sound.ko >> Reading symbols from /boot/kernel/linprocfs.ko...Reading symbols from >> /boot/kernel/linprocfs.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/linprocfs.ko >> Reading symbols from /boot/kernel/linux.ko...Reading symbols from >> /boot/kernel/linux.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/linux.ko >> Reading symbols from /boot/kernel/reiserfs.ko...Reading symbols from >> /boot/kernel/reiserfs.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/reiserfs.ko >> Reading symbols from /boot/kernel/logo_saver.ko...Reading symbols from >> /boot/kernel/logo_saver.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/logo_saver.ko >> Reading symbols from /boot/modules/rtl8180_sys.ko...done. >> Loaded symbols for /boot/modules/rtl8180_sys.ko >> Reading symbols from /boot/kernel/if_ndis.ko...Reading symbols from >> /boot/kernel/if_ndis.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/if_ndis.ko >> Reading symbols from /boot/kernel/ndis.ko...Reading symbols from >> /boot/kernel/ndis.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/ndis.ko >> #0 doadump () at pcpu.h:246 >> 246 pcpu.h: No such file or directory. >> in pcpu.h >> (kgdb) #0 doadump () at pcpu.h:246 >> #1 0xc08823c7 in boot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:416 >> #2 0xc08826b9 in panic (fmt=Variable "fmt" is not available. >> ) at /usr/src/sys/kern/kern_shutdown.c:579 >> #3 0xc0bb346c in trap_fatal (frame=0xe3744a04, eva=3303703322) >> at /usr/src/sys/i386/i386/trap.c:933 >> #4 0xc0bb36f0 in trap_pfault (frame=0xe3744a04, usermode=0, eva=3303703322) >> at /usr/src/sys/i386/i386/trap.c:846 >> #5 0xc0bb40d5 in trap (frame=0xe3744a04) at >> /usr/src/sys/i386/i386/trap.c:528 >> #6 0xc0b96a4b in calltrap () at /usr/src/sys/i386/i386/exception.s:165 >> #7 0xc4df96b3 in ndis_rtl8180_sys_drv_data_start () >> from /boot/modules/rtl8180_sys.ko >> Previous frame inner to this frame (corrupt stack?) >> (kgdb) >> >> >> ------ Last lines from dmesg -------- >> Tue Sep 22 01:02:49 BRT 2009 >> Sep 22 01:02:55 borges login: ROOT LOGIN (root) ON ttyv0 >> warning: KLD '/boot/modules/rtl8180_sys.ko' is newer than the linker.hints >> file >> ndis0: <Realtek RTL8180 Wireless LAN (Mini-)PCI NIC> port >> 0xe800-0xe8ff mem 0xdffffc00-0xdffffcff irq 16 at device 6.0 on pci1 >> ndis0: [ITHREAD] >> ndis0: NDIS API version: 5.1 >> ifa_add_loopback_route: insertion failed > > Try to enable debug.ndis sysctl.
