A running iostat via ssh continues to give output for a while, the serial console still reacts to return and prompts for login. But after a while more and more locks up. The console locks as soon as I sysrq-t. Maybe it has also something to do with the place where I added the printks (btrfs_scan_one_device). Also the 10k-print gets triggered several times (though I only see 10 lines of output). Maybe you can send me your test-module and I'll try that, so we have more equal conditions. What also might help: the maschine I'm testing with is a quad-core X3450 with 8GB RAM. -- To unsubscribe from this list: send the line "unsubscribe linux-tip-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
