Thanks to commit "kernel: Apply user iframe determination logic to SMAP/SMEP" now when disable ati accelerator and run Haiku in Vesa mode, i have a monit about unrecognition video output. I use a DVI output and a Jessica EFI to boot up.

Still an issue after hrev52314? If so does disabling SMAP in the bootloader help?

Hi, when I'am use 'use fail-safe graphics driver' in safe boot menu, system reset , don't go as at beta 1. I test in hrev52597 64 bit. When I'am disable SMAP, in safe boot menu, Haiku load fine with VESA. OF course option 'use fail-safe graphics..' must be enabled.

small errata: only with disable SMT (no theards) and safe mode Haiku load to desktop.
