The problem persistis. The server still works, now on FreeBSD 14.1. BIOS
upgrade does not solve the issue. The network hungs every day, from 1 to 10
times per day. 

I don't use BMC. My DC prices 100baseTX<full-duplex> cheaper than 1000baseTX,
and this bandwidth is enough for this server. 

By the way, other issue with this machine was SATA hung (something like
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229745 ). It worked around by
disabling hot-plug option in BIOS and reducing SATA speed: 
    hint.ahcich.[0...5].sata_rev=2
in loader.conf. Maybe, the latter is redoundant, I have no time to test without
this option. But enabling hot-plug guarantees SATA hung in a few hours after
boot.

Changing the cables does not solve the issue. 

I will attach new pair of dumps from the watchdog.

With best regards,
    Vladislav
