Hi, i tried V0.7.7 and since all other RP kernels locked for me in X, i decided to go to the console and try to see if i get some debugging output. Well i put the usual stress on the system but besides some higher rtc_wakeup jitters [up to 60%] which didn't show during the earlier runs that locked when in X, the system ran fine. i wasn't able to lock the system from within the console (X was started but idling at gdm). Ok, so i suspected, maybe the locks i see got to do with X, so i changed to the X console, logged in and quicklky switched back to the console. and no surprise 10seconds later or so it locked (i suppose gnome was still loading at that point in time). Without any console output. Does it matter which virtual text console one is on? i thought not. anyways. i might just get myself a serial console in a few days (old pc froma buddy). but i thought a serial console would be mostly useful to capture more of the debug messages. if none shows at all it won't help either right? flo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
