Closing as infra-flake and dupe of #97968.

Failed with

 storage/pebble.go:1585 â‹® [T1,n4,s4,pebble] 1347 disk stall detected: disk slowness detected: syncdata on file 000070.log has been ongoing for 20.2s

Similarly to #136082 this may be something where we are causing the disk overload during the recovery from the partition. Both tests failed after iptables was removed and the partition was resolved.
