Panic "sleeping thread" with qlnxe driver

Leonardo 2

Dear pfSense community,

I am experiencing problems with using the qlnxe driver for using a QLogic 41000 series device.

The system crash occurs simply by enabling or disabling a VLAN interface created on a NIC .

I assume that the operation triggers a series of hotplug events that are handled by pfSense and this raises critical runs that generates conflicts.

Attached is the crash report.

Best regards
