           Summary: cache_manager_rewrite: Bugcheck when starting Opera 8.51
           Product: ReactOS
           Version: unspecified
          Platform: VMWare 5
        OS/Version: ReactOS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Kernel
        AssignedTo: ros-bugs at reactos.com
        ReportedBy: navaraf at reactos.com

Using ReactOS from the cache_manager_rewrite branch, when I try to start Opera
and the system goes low on free physical memory it crashes in the
MmPageOutPhysicalAddress function at line ~301. The memory area type is
MEMORY_AREA_CACHE_SEGMENT and it probabaly got populated during a page fault on
one of the cache manager section. I believe it shouldn't even be marked as
MC_USER memory (and thus the "working set" trimming shouldn't even process it)
when the physical page is allocated and that MC_CACHE should be used instead.
Unfortunately I'm not sure how would that be handled in the modified page writer...
