Today's update (kernel and liblircclient0) did not help.
Here is some more info:
1/ Once the machine is booted, pluging in the USB receiver gives these kernel
messages:

2/ Sending an IR signal to the receiver with the remote gets me a OOPS
from which the system does not recover. See picture attached.
3/ Once rebooted via a hard reset, unplugging the receiver gives the following
kernel error message:
