My Alder Lake has only run CURRENT as it is most likely going to get
graphics support and a fix for hte file system crashes first.

Sadly, disabling soft updates does not fix the problem. I got one more VFS
crash after disabling them. Still, a single dump while building around 1000
ports is a huge improvement! Having soft updates enabled clearly makes the
likelihood of a crash much greater. I have opened ticket 266145 on this
problem if you want to see if this goes anywhere. Since it looks like a mix
of performance and efficiency core will be hte norm from now on from both
Intel and AMD, this clearly will need some attention soon.
