> It'd be interesting to see if just the data structure expansion:
Nice guess.
It still crashes on boot.
Details:
1) Working in your 2.6.16-rc5-mm1 stack.
2) Commented out gregkh-driver-put_device-might_sleep.patch
3) With gregkh-driver-empty_release_functions_are_broken.patch on top
4) Then push your "just the data structure expansion" patch on top of that
5) If CONFIG_DEBUG_SPINLOCK and CONFIG_DEBUG_SPINLOCK_SLEEP enabled:
dies trying to boot
6) But if these SPINLOCK debug are not enabled:
boots fine
The boot panic this time looks like the others at first glance:
