OPNsense 19.7.6-amd64 - Intel 82541PI - In/out errors

[bobbis]

Hi,

i am using OPNsense 19.7.6-amd64 (nano), with an Intel Networkcard

Code Select Expand

em0@pci0:14:7:0: class=0x020000 card=0x13768086 chip=0x107c8086 rev=0x05 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82541PI Gigabit Ethernet Controller'
    class      = network
    subclass   = ethernet


and from dmesg:

em0: <Intel(R) PRO/1000 Legacy Network Connection 1.1.0> port 0xb000-0xb03f mem 0xfe320000-0xfe33ffff,0xfe300000-0xfe31ffff irq 20 at device 7.0 on pci3

i have set the Network Speed for my LAN Networkcard to "Ethernet 100baseTX <full-duplex>" but i get In/Out errors with that speed:

Does someone know what i can do fix this In/Out Errors ? I dont really like to get back to 1000BaseT cause , first the card is getting very hot with 1000BaseT, secondly: i dont need 1000BaseT and at least it save energy. Would be fine if someone knows a resolution for that.

Thats in advanced.

Mostly it's cables and switches, sometimes it's hardware,. maybe in conjunction with high traffic spikes.


Cheers,

I get only IN/OUT Error in this Ethernet 100baseTX <full-duplex> speedmode, other speedmode runs without any problems... there is/was an discussion on the freebsd mailinglist about that, i dont have the link by hand sorry. So its an driver issue!
