Hi, The OHCI IRQ rate is too high. It should never exceed 1000 IRQ/s. Maybe you can build a kernel with "options USB_DEBUG", then run the following command and post some of the resulting dmesg: sysctl hw.usb.ohci.debug=16 ; sleep 1; sysctl hw.usb.ohci.debug=0 --HPS > > #7 0x8059139b in fxp_new_rfabuf (sc=0x8564c000, rxp=0x8564c1c0) > at /usr/src/sys/dev/fxp/if_fxp.c:2611 > #8 0x8059285b in fxp_intr (xsc=0x8564c000) > at /usr/src/sys/dev/fxp/if_fxp.c:1931 > #9 0x8067b1db in intr_event_execute_handlers (p=0x8553d7f8, > ie=0x8557d080) > at /usr/src/sys/kern/kern_intr.c:1220 > #10 0x8067c8eb in ithread_loop (arg=0x856525d0) > at /usr/src/sys/kern/kern_intr.c:1233 > #11 0x80678f11 in fork_exit (callout=0x8067c880 <ithread_loop>, > arg=0x856525d0, frame=0xd80e7d38) at /usr/src/sys/kern/kern_fork.c:844 > #12 0x80931de0 in fork_trampoline () at > /usr/src/sys/i386/i386/exception.s:270 > > And also unrelated to usb, but fairly bizarre "netstat -m" output: > > 18446744073709550887/1355/626/25600 mbuf clusters in use > (current/cache/total/max) > 18014398509480560K/3497K/2073K bytes allocated to network > (current/cache/total) > > Sorry for all the extra noise, but I'm not adept enough at determining > whether this panic was usb related or fxp related. > > Thanks, > > Charles > > > --HPS _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "[email protected]"
