Wow one year after
I got the same problem with a NETGEAR WG511, the firmware loads successfuly and then:
eth0: device soft reset timed out
eth0: timeout waiting for mgmt response
<repeat above 3x>
eth0: mgmt tx queue still full
<repeat above 16x>
Tried all "google tips" and nothing, i'm unable to modify my BIOS IRQ settings.
Thanks in advance
