Update: I dropped the keyspace, the system keyspace, deleted all the data and started from fresh state. Now it behaves correctly. The previously reported state is therefore the result of the keyspace being dropped beforehand and recreated with no compression on sstables - maybe some sstables were left in system keyspace as live though the keyspace was completely dropped?

If you have a reproduction path, I recommend filing a JIRA in the Apache Cassandra JIRA.

It's possible the response will be that dropping and recreating things (CFs, Keyspaces) is currently problematic and will be fixed soon, but your case seems particularly unusual/severe...
