DHCP issues with V73

[papachumba]

Just tried upgrading one of the t-22 phones we have in the office to 7.73.0.50.
Upon reboot, the phone does not want to get the IP address via DHCP, and just stays on the screen saying "obtaining IP address".
I have left it on here for longer than 10 minutes, the message doesnt go away.
I tried restarting the phone several times, no effect.
I tried connecting a power supply to the phone, then disconnecting the network cable and plugging it back in - the page refreshes and the phone obtains the new IP via DHCP. This seems to be the only trick to get DHCP to issue an IP to the phone.

I then tried both .50 and .40 versions of v73 firmwares you have available, both are exhibiting this problem, tested on several t-22 phones. Each time after the firmware update and a reboot the phone will get stuck on "obtaining IP address" screen.

I then downgraded the phone to 7.72.0.80 and upon a reboot the phone obtained the IP via DHCP without issues.
