thanks for your fixes, I couldn't make my test system panic any more.
But there's a strange thing:
I've been doing a
fssconfig -u fss0; rm /home/snaps/snap0; fssconfig fss0 /home /home/snaps/snap0
in a loop, while a bonnie++ was running in another loop. And I see:
/home: suspended 80.452 sec, redo 1217 of 2556
/home: suspended 226.932 sec, redo 1177 of 2556
/home: suspended 350.192 sec, redo 1206 of 2556
/home: suspended 477.433 sec, redo 1205 of 2556
/home: suspended 635.357 sec, redo 1208 of 2556
/home: suspended 813.420 sec, redo 1201 of 2556

any idea why is takes more and more time to take the snapshot ?
