Test conditions exactly the same, fsx-linux in one window, LTP in another window. The machine stays alive for pings and sysrq's, but I cannot ssh into it nor login at the console. sysrq-s initiates a sync of the root filesystem on the ATA disk but never finishes. other sysrq's and pings continues to work after the sysrq-s invocation.
