Description (last modified by )
Booting Haiku hrev55207 x86_64 on a Dell Latitude e6430 laptop using EFI results in a blank screen (once all the boot icons have been successfuly displayed/lit-up), then KDL after a few minutes. Booting using framebuffer does not generate any issue, so looks related to recent work on the Intel Extreme driver.

Hi, Thank you. Can you please also upload a syslog from the last known to you working version of the driver for my reference if possible?

Thank you. I expect it's the pipe assignment that's causing trouble for you (B=OK, A fails). I will look into it asap, but I can't update the driver until next week I'm afraid. I'll keep you posted!

Since yann64 wrote on discuss.haiku-os.org:
Ticket can be closed as invalid. Driver is working when booting from USB and from clean install. Somehow my install got corrupted. Sorry for the noise.
Closing ticket. Looks like pipe A does work.
If you could upload a new syslog that would be nice for confirmation!
Thanks!

Thank you. Pipe A is in use and looks OK indeed. It's preprogrammed by the BIOS to 18-bit colordepth for the panel as well. Which is an indicator the BIOS also uses this pipe.
Though FDI isn't actually used if all is right (panel on north/cpu side I assume). For your native mode two lanes would be needed while only 1 is operational from the looks of it.
