Description
How to reproduce: Boot hrev28255 in a NEC Versa M360 laptop.
Experienced behavior: Crashes with assertion fail.
src/add-ons/kernel/bus_managers/ata/pio.c:166: ASSERT((physicalAddress & 4097) == (virtualAddress & 4097))
This crash started occurring after the hrev28244 changes.
I could boot Haiku with no problems after disabling the assertion checking in the source code, but I don't know if it's safe.
My patch is attached, although I don't know if it's safe.

Seems I ran into the same failure on my core 2 duo box using hrev28255.
Considering I haven't used this machine in a while, i'm not sure what caused this.

Removing the ASSERT is vertainly not a good solution, when you don't understand whats going wrong.
Probably caused by hrev28244, reassigning to bonefish.

Fixed in hrev28257. The assert was broken. It only worked with the old page mapper, because it would map the physical page to a virtual address with the same 4 MB modulo.
Patch that fixed my problem (I don't know if it's safe)
