newfs_msdos: sysctl: KERN_MAXPHYS, using 1048576: Cannot allocate memory

Hi,

I have options MAXPHYS=131072 in my kernel. This fixed the issue I was having with the built-in sata controller. However, when I try to create a fat filesystem, I get:
Code: 
# newfs_msdos /dev/da0s1
/dev/da0s1: 2146959424 sectors in 33546241 FAT32 clusters (32768 bytes/cluster)
BytesPerSec=512 SecPerClust=64 ResSectors=32 FATs=2 Media=0xf0 SecPerTrack=63 Heads=255 HiddenSecs=0 HugeSectors=2147483648 FATsecs=262081 Ro2
newfs_msdos: sysctl: KERN_MAXPHYS, using 1048576: Cannot allocate memory
It doesn't matter what drive I try to create it on. It can be a thumb drive and I get that warning. Since it is just a warning, it does create the filesystem. However, it looks like sysctl can not see the size of KERN_MAXPHYS. Is there a work around for this issue?

Thanks!
 
Maybe circle back to why you've set it in the first place.

What issue? What did it resolve?

MAXPHYS was defined as 128K (131072) in earlier versions, on 13.0 it was bumped up to 1MB (1048576). So I would really suggest not setting it at all.

MAXPHYS bump for FreeBSD 13

The change to MAXPHYS in 13 means my system would not boot at all or if it did boot the filesystem was forcably unmounted when I tried to write to it. This is the error I get without it:
