system boot hang due to inteldrm(4)

Jan Klemkow
Hi,

After updating my router to current, the systems hangs during the boot.
Maybe its caused by the "invalid EDID"?!  The System boots up normaly
and doesn't hang, if I disable inteldrm(4) in UKC.

Is this issue known?  Or, witch additional debug information should I
provide to help fixing this bug?

Thanks,
Jan

Building a kernel with 'option DRMDEBUG' will give more information.

Is the machine hooked up to a kvm or monitor?

What Lanner model is this?  "gbXSo" doesn't help.

Hi Jonathan,

> Building a kernel with 'option DRMDEBUG' will give more information.

See the log below:

> Is the machine hooked up to a kvm or monitor?

No KVM and no monitor.  Just serial access.

> What Lanner model is this?  "gbXSo" doesn't help.

Lanner LEC-7233

Thanks,
Jan
