The following kernel crash noticed on qemu-arm64 while running the Linux next-20241210 tag (to next-20241218) kernel built with

• CONFIG_ARM64_64K_PAGES=y
• CONFIG_ARM64_16K_PAGES=y

and running LTP smoke tests.

First seen on Linux next-20241210. Good: next-20241209 Bad: next-20241210 and next-20241218

qemu-arm64: 9.1.2

Anyone noticed this ?

Anders bisected this reported regression and found, # first bad commit: [9c1d66793b6faa00106ae4c866359578bfc012d2] btrfs: validate system chunk array at btrfs_validate_super()

Thanks, I'll drop the patch from linux-next for now.
