Can you get a backtrace in ddb? It looks like a null pointer dereference, and knowing where it happened would help. Finding the file and line of the instruction pointer using addr2line on kernel.debug would be helpful as well. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Joe and I looked at this problem, and it seems a function called device_get_ivars() isn't doing its job in sys/dev/usb/usb_port.h. So the variable is getting filled with a NULL pointer for the iface element and is later deref'd. That's the limit of my debugging, and Joe is looking into the problem actively.

Well, if device_get_ivars() is returning a NULL pointer, then it probably means its parent bus device isn't setting up the ivars for the child device properly. As far as I understand, you can think of ivars as being per-device variables or state often used by a parent bus to set bus-specific information for a child device. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: plug aue ethernet goes to panic
device_set_ivars is always called (in usbd_probe_and_attach) with as an argument a stack variable. Also, the ivar is not stored or anything in the if_aue.c driver. So this problem sounds like a problem in revisions of various files. Please check that your kernel modules kernel are in sync. Do this by rebuilding the kernel and the modules from scratch. Also, after you've installed your kernel check that all your kernel files have been updated. Do you by any chance have a stale /modules or /boot/modules directory lying around? You should have only kernel modules in /boot/kernel*/ and NOT in /modules* or /boot/modules*. If the problem persists, please mail me the output of ident /sys/dev/usb/*.[ch] find /modules /boot -type f -ls Thanks.

He's already confirmed that it *is* an issue in the code (and not any kind of misconfiguration on my part). I've already spent enough time debugging the problem. I recently MFC'd the support for my device to -stable so I could use the machine on the network without it panicking on me. However, when Joe fixes the problem I will give it another shot [same machine has -CURRENT on another partition that I use for occasional hacking]. Thanks for the suggestions, though.

Nick, I've introduced a probe and attach bug somewhere with aue, and I'm guessing with cue and kue too. I'm gradually getting to the bottom of it, but this is the first time I've gone near the attach code so it's taking me longer than it should. Joe msg37291/pgp0.pgp Description: PGP signature
