So, this is an odd one. I have a test ARM server in AWS, which I was running using a Neoverse-V1 instance type, and I compiled the system for it using CPUTYPE?=neoverse-v1 If I then change the instance type to Neoverse-V2 and boot it, then it seems to work, except I get this: 30 Apr 16:59:56 ntpdate[767]: poll() error: Invalid argument But (as far as I can tell) V2 is supposed to be 100% backward compatible with V1, so this should not make a difference. Did I misunderstand this ? My first foray into ARM! -pete. PS: If I leave CPUTYPE alone then it works on both fine by the way
Adding to my own email here, but I also just tried compiling on the V2 instance, with CPUTYPE set to neoverse-v2, and running that, and that gives the same error, which I wasn't expecting. This is also in the userland somewhere, as if I run it with a non CPUTYPE kernel, but lave the userland alone, then it still produces the error.
