Problem Description: umounting of an affs partition crashes the kernel instandly. only hardreset is left.

Steps to reproduce: just mount an affs partition, read or write something and umount the mountpoint or device. the kernel will freez instandly.
please do a sync bevore to avoid other filesystem damage.

Can you provide traces, dmesg if it is produced during crash?
And also you can try git bisect since you know last working version of kernel.
Thanks.
