21.7 and igb interface problem

[athurdent]

Hi,
I have tried various updates on my Proxmox hosted OPNsense KVM and all have failed when using my mapped igb0 interface. As soon as Sensei is started in non-passive mode, either emulated or native netmap, my Proxmox host's load goes up to 150 and OPNsense is no responsive anymore.
Using the VTNET interface only, no problem. Adding the igb0 interface, OPNsense is no longer responsive.

Hi,

Did you try Sensei in Bypass Mode (Status - Services - Sensei Packet Engine- Enter Bypass Mode)?

[athurdent]

Hi,

no, I would have to set it to bypass mode and afterwards switch from passive mode to a netmap mode.
Switching to a netmap mode with the igb interface active instantly kills the OPNsense, no way to get to bypass mode then. I can only restore from a snapshot to get it working again.
Should I try switchting to a netmap mode with bypass mode on, would that help you debugging the problem?

[athurdent]

OK, just tried to switch on native netmap mode while in bypass. That seems to disable bypass and also kills OPNsense.

Hi,

It seems that it is a netmap issue. Please send a bug report from the upper right corner of Sensei GUI by selecting all checkboxes.

Thanks & done!

Hi,

I didn't get yet. Can you send again?

[athurdent]

Hi, now it worked I guess. Did not get a ticket mail the first time, it's there now though.

Just updated fine, newer kernel is on the default repo.
No more hangs, great work, guys!
