This bug is awaiting verification that the linux/6.2.0-36.37 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-lunar-linux' to 'verification-done-lunar-linux'. If the problem still exists, change the tag 'verification-needed-lunar- linux' to 'verification-failed-lunar-linux'.
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 only reason this wouldn't work properly is if sgx_drv_init thinks XSAVE isn't enabled. This works fine in 5.15.0-1043. Likely cause: 1045 adds this patch: https://github.com/torvalds/linux/commit/b81fac906a8f9e682e513ddd95697ec7a20878d4 . This later patch indicates that the former patch introduced some ordering problems. https://github.com/torvalds/linux/commit/2c66ca3949dc701da7f4c9407f2140ae425683a5 . That later patch isn't applied to 1045. [Test Plan] User test results pending, but its a fix commit so should likely be applied regardless. [Regression Potential] SGX could continue to fail.
