Our firmware level looks ok, higher than you suggested. ConnectX-5 Firmware version: # mstflint -d 0000:01:00.0 q Image type: FS4 FW Version: 16.23.1020 <<<<<<<<< FW Release Date: 10.7.2018 Product Version: 16.23.1020 Description: UID GuidsNumber Base GUID: ec0d9a0300cab17c 4 Base MAC: ec0d9acab17c 4 Image VSD: N/A Device VSD: N/A PSID: IBM0000000020 Security Attributes: N/A I have chased the -95 into the ib_uverbs modules, the error is returned from uverbs_request_finish(), called from ib_uverbs_ex_create_rwq_ind_table(). If I understand, the purpose of uverbs_request_finish() is to verify that the unused portion of some part of buffer passed in from userspace is filled with NULLs. The error indicates its not. If I remove the call to uverbs_request_finish() testpmd starts up fine, but I cant say its functioning beyond that. I am thinking some incompatibility between libibverbs and the ib_uverbs. There have been recent changes with this kernel interface that may be new for the 5.0 kernel. I am trying to correlate the user space structures with the kernel, but I am struggling at the moment. Thank you for for testing on x86, I agree its time for me to reach out to Mellanox. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823836 Title: dpdk app is reporting: net_mlx5: probe of PCI device xxxx aborted after encountering an error: Unknown error -95 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1823836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
