Hello, I am holding off on this update because it has caused severe regressions, and more issues are still being found with it.
The most immediate regression was reported very quickly by users, and was reverted next-day by Intel (release 20260812), but there are other updates still in 20260812 that cause boot hangs on Xeon servers with older microcode/firmware, for example. I.e. it is the dreaded "update incompatible with older system firmware" problem showing it face once again. The current recommendation is: update your system firmware, push your vendor for them to properly issue firmware updates if need be.
