I do not enable interrupts between SystemACE and the CPU. Following the
debug cycle:

xsysace_init()
->register_disk()
-->grok_partitions()
--->check_partition()
---->msdos_partition()
----->read_dev_sector()
------>read_cache_page()
------->lock_page()
-------->__lock_page()
--------->schedule()

And it never resumes after that. The code just goes to power_save mode.
Any help would be appreciated.
