Hmmm... I don't see anything that sticks out in the sysrq info (well, not sure if the do_wp_page() is just trace junk or not - CC'ed Peter just in case). Maybe this is related to the expand files OOM thing that Martin saw? If you boot w/ init=/bin/bash do you also see the hang? If you execute "date" a few times, does it seem to keep proper track of time? Also could you enable softlockup detection? (CONFIG_DETECT_SOFTLOCKUP) Which you can find under Kernel debugging in the make menuconfig. thanks -john - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
