Hi,

thanks for your response.

Here some more information dumped on 5.18.0-rc1:

In the dump above the UUID was missing so here is the missing line:
ALERT! UUID= e575c8fb-4c2a-47ec-973e-4a52cdd2ebdf does not exist. 
Dropping to a shell!

cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sdb2 during installation

BA665B75665B317D                     ntfs     /dev/sdc4
                                               /dev/sr0

But the question remains. What has changed from rc1 to rc2 that cause 
the hang?

Thanks
