Can you please share below details? 1) Model and Manufacturer of the system 2) Linux distro/kernel used?4.13.3 gets a little further, but after some more data is transferred the tg3 driver still crashes. This is unfortunately before I've got a writeable filesystem. The last line is: tg3 0000:01:00.0: tg3_stop_block timed out, ofs=4c00 enable_bit=2 I've got some ideas to get the full dmesg. As with the other kernels it works OK on 1Gbps, but not slower switches.I am suspecting with link aware mode, the clock speed could be slow and boot code does not complete within the expected time with lower link speeds. So, Providing a patch to override clock. Can you please try with attached debug patch and provide us the feedback with 100M link? If it solves this issue, we will work on proper changes.This does work on 4.13.3 and PXE for me. I've tested on 1 Gbps, 100 Mbps and 10 Mbps. I've done some preliminary testing (eg. large file copies.)
Good. We will work on required changes and upstream proper patch after sanity test with multiple speeds.
