Public bug reported:
Description:
On Ubuntu 24.04 (linux-6.8) Azure instances, MANA-accelerated NICs fail to
initialize during device probing, leaving the network interface unusable.
Logs (dmesg):
kernel: mana 7870:00:00.0: HWC: Failed hw_channel req: 0xc00000bb
kernel: mana 7870:00:00.0: VfVerifyVersionOutput: -71, status=0xc00000bb
kernel: mana 7870:00:00.0: gdma probe failed: err = -71
This could be related to missing upstream commit: 7fc45cb68696 ("net: mana:
Allow variable size indirection table").
To reproduce, with a MANA NIC provisioned, boot on the following linux package
installed:
linux-generic-6.8/noble-updates,noble-security,now 6.8.0-137.137
Thanks
