Network problems (actually bad power supply)

[ykanello]

Hello all,
I am having network timeouts towards all SoC of the clusterboard.
After reading the posts with regards to the PSU, I removed two SoC and now is running with 5, but the problem still persists.
I do not have the time drift problem (date set to a far future) anymore after I installed the recommended kernel package from the community. [linux-image-next-sunxi64_5.99_arm64.deb]

I rely heavily on the network of the clusterboard and this timeout issue makes the clusterboard quite useless for me.
Does any one have a solid idea on what the problem could be?

Sample of the timeouts:

Code:

64 bytes from 10.13.3.74: icmp_seq=600 ttl=64 time=2.118 ms
Request timeout for icmp_seq 601
Request timeout for icmp_seq 602
Request timeout for icmp_seq 603
Request timeout for icmp_seq 604
64 bytes from 10.13.3.74: icmp_seq=605 ttl=64 time=1.943 ms
64 bytes from 10.13.3.74: icmp_seq=606 ttl=64 time=2.017 ms

thanks
