Reproducible panic when running usbdump. First usbdump seems to run okay. Stop it and run again later and panic happens. Command was: usbdump -d 0.3 -s 0 -v Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x10 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80c5c6eb stack pointer = 0x28:0xfffffe00c6255d60 frame pointer = 0x28:0xfffffe00c6255d60 code segment = base rx0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 15 (usbus0) rdi: fffff8021a0da000 rsi: 0000000000000000 rdx: fffffe0117d86278 rcx: fffffe0117d86278 r8: 0000000000000000 r9: 0000000000000300 rax: 0000000000000000 rbx: 0000000000000000 rbp: fffffe00c6255d60 r10: 0000000000000004 r11: 0000000000000310 r12: fffffe00c659c428 r13: fffff8001c194438 r14: fffff8001c194438 r15: fffffe00c659c428 trap number = 12 panic: page fault cpuid = 0 time = 1746349882 KDB: stack backtrace: #0 0xffffffff80b9083d at kdb_backtrace+0x5d #1 0xffffffff80b426a1 at vpanic+0x131 #2 0xffffffff80b42563 at panic+0x43 #3 0xffffffff81034b7a at trap_pfault+0x3da #4 0xffffffff8100b508 at calltrap+0x8 #5 0xffffffff8095014a at usbpf_xfertap+0x3a #6 0xffffffff809583cc at usbd_pipe_start+0x13c #7 0xffffffff809574f6 at usb_command_wrapper+0x96 #8 0xffffffff80955c03 at usbd_callback_wrapper+0x5c3 #9 0xffffffff809574f6 at usb_command_wrapper+0x96 #10 0xffffffff80956189 at usb_callback_proc+0xb9 #11 0xffffffff80950bbe at usb_process+0xfe #12 0xffffffff80afba5f at fork_exit+0x7f #13 0xffffffff8100c56e at fork_trampoline+0xe Uptime: 8m26s Dumping 856 out of 16224 MB:..2%..12%..21%..32%..42%..51%..62%..71%..81%..92%
Oh, should have said: 14.3-STABLE from 2025/02/03 approx 11:30 UTC.
Correction to the above: 14.3-STABLE from 2025/05/03 approx 11:30 UTC. Not 2025/02/03!
I can not repeat this on either current/15 or stable/14. What's your usb device 0.3 ? Can that also be repeated on 14.3-BETA2 ?
The device is: ugen0.3: <vendor 0x0b0e BTV5.2> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (0mA) bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0200 bDeviceClass = 0x0000 <Probed by interface class> bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x0b0e idProduct = 0x24c8 bcdDevice = 0x0112 iManufacturer = 0x0001 <> iProduct = 0x0002 <BTV5.2> iSerialNumber = 0x0003 <00ff905B0200> bNumConfigurations = 0x0001 In plain English, it is a vendor "GN Netcom" device "Jabra Link 380" which is a USB to Bluetooth dongle. In my case, it is driving a Bluetooth headset. I will pull the latest 14/stable and report back if this still happens there.
Just pulled latest 14-stable as of 2025/05/16 09:50 UTC: FreeBSD x.y.z 14.3-STABLE FreeBSD 14.3-STABLE stable/14-n271493-d7837cac6f64 GENERIC amd64 I have been able to run this usbdump multiple (about 10-15) times so far without problems. So, perhaps not a problem now. I will close this ticket in a few days if there are no further problems, or I'll add more details if there are.
