Everything was hung - the compile, Gnome, everything - and I didn't seem to be able to get out with and key combination so I did a hard reset. 2) I tried rebooting into 2.6.17-rt8 and hung during the boot process. I managed to catch one not-so-good photo (the flash was on) showing the "3-level deep critical section nesting". Let me know who to send it to off list. The end shows something like: __sched_text_start+0x3b/0x58f...[<00000000>] <=0x0 rt_lock_slowclock_)x30/0x23e...[<00000000>] <=0x0 rt_lock_slowclock_)x30/0x23e...[<00000000>] <=0x0 Up above there is some stuff like: rt_lock_slowdown get_page_from_freelist get_zeroed_page pte_alloc __handle_mm_fault. do_(something I cannot read) do_(somethign I cannot read) debug_(something)_mutex_unlock error_exit Unfortunately stuff in there is blanked out by the flash reflecting on the screen. (Stupid me! Sorry!) I've gone back to 2.6.17-rt5 for now which has been running great and never crashed on me. I hope this little bit helps confirm some of what you all are debuggin in your other threads.
