Ouch, looks like I hit an incarnation of kern/32570 (miibus compiled into kernel for if_de but the module is additionally loaded on boot as a dependency for if_vr.ko) After compiling both de & vr into the kernel, the problem goes away. -- "Gemischte Materialien // Früher: Restmüll" Aufschrift auf einem Container, Informatik-Parkplatz http://lambda.foldr.org/~vs/ * PGP * S/MIME State Changed From-To: open->closed Closed at originators request. |
The following NIC crashes the system on invoking "ifconfig vr0" after producing two lines of output (after MAC): vr0: <VIA VT6102 Rhine II 10/100BaseTX> port 0x10000-0x100ff mem 0x81050000-0x810500ff irq 9 at device 12.0 on pci0 vr0: interrupting at ISA irq 9 vr0: Ethernet address: 00:05:5d:5f:55:d3 miibus0: <MII bus> on vr0 ukphy0: <Generic IEEE 802.3u media interface> on miibus0 ukphy0: no media present ... fatal kernel trap: trap entry = 0x2 (memory management fault) a0 = 0x10 a1 = 0x1 a2 = 0x0 pc = 0xfffffc00006aaa18 ra = 0xfffffc000036f384 curproc = 0xfffffe0003992980 pid = 336, comm = ifconfig panic: trap (kgdb) where #0 0xfffffc00003a9b00 in dumpsys () at /usr/src/sys/kern/kern_shutdown.c:486 #1 0xfffffc00003a9648 in boot (howto=256) at /usr/src/sys/kern/kern_shutdown.c:316 #2 0xfffffc00003a9ef0 in panic (fmt=0xfffffc00005b4c9c "trap") at /usr/src/sys/kern/kern_shutdown.c:595 #3 0xfffffc000055663c in trap (a0=16, a1=1, a2=18446741874755137120, entry=0, framep=0xfffffe000470bb10) at /usr/src/sys/alpha/alpha/trap.c:551 #4 0xfffffc00005482dc in XentMM () #5 0xfffffc000036f384 in mii_pollstat (mii=0xfffffe000045f380) at /usr/src/sys/dev/mii/mii.c:328 warning: Hit heuristic-fence-post without finding warning: enclosing function for address 0x4 (kgdb) up 5 warning: Hit heuristic-fence-post without finding warning: enclosing function for address 0x4 #5 0xfffffc000036f384 in mii_pollstat (mii=0xfffffe000045f380) at /usr/src/sys/dev/mii/mii.c:328 328 (void) (*child->mii_service)(child, mii, MII_POLLSTAT); (kgdb) list 323 mii->mii_media_status = 0; 324 mii->mii_media_active = IFM_NONE; 325 326 for (child = LIST_FIRST(&mii->mii_phys); child != NULL; 327 child = LIST_NEXT(child, mii_list)) 328 (void) (*child->mii_service)(child, mii, MII_POLLSTAT); 329 } (kgdb) print child $3 = (struct mii_softc *) 0xfffffe000045f380 (kgdb) print child->mii_service $4 = 0xfffffc00006aa9c0 I'll extract more information if somebody wants to walk through it (or I put up the files somewhere).
