The isofs crash is fixed in 21ee0e79.  Please update your Hurd packages.

The fact that you are seeing these messages is a (quite nice actually)
side-effect of 234568d0.  I guess that if you were doing this on a Linux
machine, you would see these in the kernel ring buffer. 

OK, I updated my Hurd system using the Debian ports repository.  The package is hurd-0.8.git20160522, and it includes 21ee0e79.

Sure enough, the crash is gone, but I still get the error messages:

ext2fs: /dev/hd0s2: panic: main: device too small for superblock (1024 bytes)
/hurd/fatfs: Invalid number of bytes per sector
/hurd/iso9660fs: Could not find valid superblock

Are you suggesting that these are to be expected?  Is this a bug in update-grub?  These messages seem awfully severe for a standard system operation.
