Hi,

I tested your git rep before kernel 4.4 commit and after it.

I have Dlink DSL-624 and DSL-524. They have identical hardware. The former has a Wifi card.

I have already tested John's (blogic)) repo when he tried to port AR7 to 4.4 and reported back.

These are the results:

before 4.4 commit (kernel 3.18.29):
 * Ethernet ports work (ping works)
 * via UART, boot msgs appear almost normal except two/three lines
 * also via UART, greeting msg and results of commands appear scrambled however,
   late msgs from boot like   random: nonblocking pool is initialized  still appear normal

after 4.4 commit:
 * no response from pinging at 192.168.1.1. In some rare cases I get only one response during early boot.
 * large portion of boot msgs get omitted after 10 seconds
 * no results are shown when issuing commands via UART.

These issues happened exactly the same as John's attempt to port 4.4 two months ago

Mohammed,

here are bootlogs:
