I ran the following tests on a ThunderX2 system with the patched kernel: for i in {1..100}; do sudo ipmitool sensor list; done for i in {1..100}; do sudo ipmitool mc info; done
The idea here is to generate a lot of data though the i2c driver, and trigger any instability that might exist. The tests did not expose any issues. ** Summary changed: - bug fixes that improve stability of the ThunderX2 i2c driver + [Bionic] bug fixes that improve stability of the ThunderX2 i2c driver ** Summary changed: - [Bionic] bug fixes that improve stability of the ThunderX2 i2c driver + [Bionic] bug fixes to improve stability of the ThunderX2 i2c driver ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Canonical Kernel Team (canonical-kernel-team) ** Changed in: linux (Ubuntu) Importance: High => Critical ** Changed in: linux (Ubuntu) Status: Incomplete => Triaged -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1781476 Title: [Bionic] bug fixes to improve stability of the ThunderX2 i2c driver Status in linux package in Ubuntu: Triaged Bug description: [Impact] With ThunderX2 i2c driver, ipmi transfers may get stuck or stack corruption might occur.

There for risk for regression is low.
