I just got another deadlock today. It was a bit better compared to the previous ones: the ssh connection I had in a xterm was still available; screen(1) was running and it was possible to change virtual terminals with Ctrl-n. All other inputs were not taken into account. The console had a bunch of the customary "Debug: pmap_interlock 00010003" messages. The last 4 lines were "bio_page_alloc: WARNING emergency page allocation" -- Francois Tigeot
