It's even harder to remote debug such a machine over a mailing list > :-) Indeed ;-) Here's my setup: Lombard with 6GB HD and 64MB RAM (just like yours I guess); my probs started with USB support compiled in the kernel: even if it does not lead to a total freeze so often (would say very seldom indeed), I still get mouse freeze under X when heavy network activity is being made (last time 5 mins ago getting a big attachment). Some other times I get a kernel panic during the boot when initializing the serial interfaces (no, I have NOT support for standard serial but only MAC serial compiled into the kernel). This is why I was thinking about some USB/serial code problem but I agree we need some debug output to work on. Using Debian 2.2 and XF86_FBDev with kernel 2.2.15pre20 from Paul's tree. Thinking about the debug way you suggest, it comes to my mind another question not so related to the prob: is there a USB->serial converter around ? Is there one of this devices supported by Linux ? On PPC ? Ciao, -- Mario Scarpa Mondonet NOC Phone: +39 06 52.47.37.02 ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
