"i40e: Fix for Tx timeouts when interface is brought up if DCB is enabled" Commit: fa38e30ac73fbb01d7e5d0fd1b12d412fa3ac3ee "i40e: prevent overlapping tx_timeout recover" Commit: d5585b7b6846a6d0f9517afe57be3843150719da The issue was hit while running on 4.15.0-38-generic #41~16.04.1-Ubuntu on Xenial (the hwe kernel). Symptoms include messages in the kernel log of the form: [4733544.982116] i40e 0000:18:00.1 eno2: tx_timeout: VSI_seid: 390, Q 6, NTC: 0x1a0, HWB: 0x66, NTU: 0x66, TAIL: 0x66, INT: 0x0 [4733544.982119] i40e 0000:18:00.1 eno2: tx_timeout recovery level 1, hung_queue 6 [4733572.116270] i40e 0000:18:00.1 eno2: tx_timeout: VSI_seid: 390, Q 2, NTC: 0x49, HWB: 0x123, NTU: 0x123, TAIL: 0x123, INT: 0x0 [4733572.116272] i40e 0000:18:00.1 eno2: tx_timeout recovery level 1, hung_queue 2 Leading to Kafka server issues, etc. We are fairly confident this is the same as the original reporter, and we'd like to use this bug to proceed on the stable release update process. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779756 Title: Intel XL710 - i40e driver does not work with kernel 4.15 (Ubuntu 18.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779756/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
