Consider the following scenario:
This problem can occur because of stale Translation Look-aside Buffer (TLB) entries in which the virtual-to-physical mapping does not match the Page Table Entry (PTE). The error occurs when the MmMapIoSpace function is called by using either MmCached or MmNoncached memory, and the stale TLB entries are not correctly invalidated. When the MmMapIoSpace function is called by using MmUncached memory, the TLB entries are correctly invalidated. The problem does not occur if the drivers use the MmMapIoSpace or the MmUnmapIoSpace functions only at load and unload time.
