Strange with the L2 caches. The kernel developers have modified the output of lscpu two weeks ago.

Simplify cpumask api usage for cpuinfo display

Thank you for testing!

It was not only in cpuinfo, L2 mising also in /sys/devices/system/cpu/...
I will measure with RAMSpeed after I will return from vacations.

Hello.

So I've been testing the alphas in the background. So far it's been a good series with each kernel running well. I did read the discussion about the L2 caches so will monitor this also and check if I also have this issue.

FYI:
