We would like to support boot device especially SAN boot over IB. So far
I can see the following issues in current code:
1) Many functions are page-able. If these functions are running at boot
or shut down time, the disk may not be ready, the paging won't work.
2) Spinlock may not work for crashdump, whose IRQL>DISPATCH_LEVEL. Any
other functions need to be changed when IRQL>DISPATCH_LEVEL?
3) All related drivers should be boot start driver.
Are there any other potential problem? Is there any plan to support SAN
