It would be great if you could help to check grub2-mkconfig with "set -x" at beginning and use $ tail -f /var/log/YaST2/y2log_bootloader and run yast2 bootloader to check where in the script is blocking or looping, we could then take a look on that them.

CNTRL+Z puts the process to background and suspend it. (In case that it holds file lock or any unreleased resource, which is unwanted side-effect to new running process) If you want a clean termination, use CTRL+C is better way to go. :) The 'trace' (set -x) is not enable in the script, you could try this command $ sed -i '1s/$/ -x/' /usr/sbin/grub2-mkconfig That is set your #! /bin/sh to #! /bin/sh -x And see where the execution blocks (in a command or in a loop).

From the log, it's obvious that grub2-probe took too many time to complete. The time spent is approx 12s each, but you have to time the value with 19.

$ grep grub2-probe bug-774560_grub2-mkcofing-strace.log | wc -l 19 The sum of time is 19x12=228s, which is ridiculous. For your reference, on my testing laptop grub2-probe completes between 0.01 to 0.02s. The difference to yours is huge. The strace output would be very helpful, would you please help to provide? $ strace -T /usr/sbin/grub2-probe --verbose --device /dev/sda1 --target=fs > grub2-probe-strace_T.log Meanwhile .. I'll try digging the code to find any suspicious, but would be much more helpful with above log.

I think the culprit is identified .. open("/dev/fd0", O_RDONLY) = 4 <12.203271> Please check your /boot/grub2/device.map and *remove* this line (fd0) /dev/fd0 This is a regression indeed, grub2 2.00 drops device.map thus we create it by YaST (I guess the grub2 created one did not have fd0). The (fd0) grub devices maps to floopy device and grub2-probe would try to open it for whatever reason and block on it for 12s. I'll try to resolve the problem (maybe a review of device.map is needed or not and probably completely drop device.map as grub2 could be installed by mutipath device names so the mapping to grub device name seems to superfluous ..)
