This bug is awaiting verification that the linux-oem-6.11/6.11.0-1023.23 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done- noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed- noble-linux-oem-6.11'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The crashes are root caused to corruption in registers used for floating point code. [Fix] They are caused by a lack of FP context protection around that code. They are fixed by these 3 commits: https://github.com/torvalds/linux/commit/afcdf51d97cd58dd7a2e0aa8acbaea5108fa6826 https://github.com/torvalds/linux/commit/366e77cd4923c3aa45341e15dcaf3377af9b042f https://github.com/torvalds/linux/commit/4408b59eeacfea777aae397177f49748cadde5ce [Test] 1. Install ubuntu with 6.11 kernel on AMD platform 2. Run reboot test around 300 times 3. The system should not hang while booting up [Where problems could occur] The 3 commits are straightforward for the protection, and didn't involve any functional changes.
