Title: SFSHandler crashes on Reboot/Shutodwn
Post by: FlynnTA on November 20, 2025, 07:07:47 PM

Hi,

I use NGFS for my Boot/AmigaOS and Work partitions. I use SFS/02 on my Backup partition.

When I reboot/shutdown my X5000 with the reboot command or via the Menu option, I see the following crash on the serial output:

I do not think that this will make any issues, but still it would be nice to fix this.

Thank you,
