[solved]kernel 4.15.15-1:UdevQt: em28xx dvb-card not working

Hi,

I'm running plasma desktop (arch), today I updated my System (-Syu) and after reboot my em28xx dvb-card isn't being recognized anymore.
There seems to be a problem with UdevQt, but I don't know how to fix it. Help is highly appreciated. smile

So...details:
kernel:

Linux 4.15.15-1-ARCH #1 SMP PREEMPT Sat Mar 31 23:59:25 UTC 2018 x86_64 GNU/Linux

Plugging in my dvb-card results in these system messages (journalctl):

The dvb-card (em28xx usb) was being recognized and working correctly before reboot after sysupdate.

Unplugging the device gives:

Apr 16 15:03:13 eccho kernel: usb 1-1.1: USB disconnect, device number 16
Apr 16 15:03:13 eccho plasmashell[3636]: UdevQt: unhandled device action "unbind"

Apr 16 15:03:13 eccho kdeinit5[3575]: UdevQt: unhandled device action "unbind" 

I reinstalled the latest version of linux-firmware-git, but that didn't help.
Maybe this is a reason:

Apr 16 14:58:41 eccho kernel: v4l2_common: Unknown symbol v4l2_subdev_init (err -22)

How can I fix the

UdevQt: unhandled device action "(un)bind"

problem ?

...any ideas ? smile

Re: [solved]kernel 4.15.15-1:UdevQt: em28xx dvb-card not working

What is the output of `pacman -Q linux` and `modinfo v4l2-common`

Re: [solved]kernel 4.15.15-1:UdevQt: em28xx dvb-card not working

That is strange as the module is for 4.15.15-1 and the running kernel is 4.15.15-1.  Is the module v4l2-common loaded as shown by lsmod?
What is the full dmesg output?

Re: [solved]kernel 4.15.15-1:UdevQt: em28xx dvb-card not working

As the device didn't work after reboot I tried the media build tree, but that didn't change the problem. After uninstalling media build, modinfo v4l2-common returns:

modinfo: ERROR: could not get modinfo from 'v4l2_common': No such file or directory

After uninstalling media build I rebooted and dmesg gave me:

[    4.354643] em28xx: Unknown symbol media_device_unregister (err 0)
[    4.354760] em28xx: Unknown symbol v4l2_i2c_new_subdev_board (err 0)

[    5.472691] em28xx: Unknown symbol tveeprom_hauppauge_analog (err 0) 

P.S.: I don't know what went wrong exactly, but reinstalling the kernel fixed the problem.
->solved.

What is the media build tree?  What commands did you run?  Why do you keep only posting excepts from dmesg?
