Ok, so I may try the SSH way, maybe I get something before network gets nonfunctional. Or maybe I didn´t even test ssh/ping and network still works. But I think I tried accessing the machine via network, I usually do this in such cases. If that does not work and USB to serial adapter might work. But then as far as I remember even audio locked up hard replaying the same sample all over again, so I do not know whether the kernel will do anything at all. Aside from that I got the idea to try to scrubbing with kernel 3.1 to verify whether thats an regression. Well I try some things and report back. Since the / filesystem on that ThinkPad T23 is the only one it might have some wierd issues. Its one of my oldest BTRFS filesystems.
