I tested kernel-7.0.14-22_bnxt-test1, in my case, the problem is gone, there are no issues in the logs regarding the bnxt_en driver, and the network is working.
Proxmox VE 9.2.21 - BCM57412 bnxt_en network failure after upgrade to kernel 7.0.14-20-pve
- Thread starter ManuS
- Start date
Just to clarify, how long does it take from the test kernel release until it becomes available on the production/stable channel for download and update?
Over 2 hours in to running today's 7.0.14-22~bnxt-test1, so issues at all so far. I've even done a 5 minute iperf3 in both directions over the bnxt_en adapters, and no issues what so ever.
Same problem whit my BCM57502
