Package: src:linux
Version: 4.3.5-1
Severity: normal
Dear Maintainer,
Booting this kernel (or the debian-installer latest daily) results in a blank
screen. When removing the quiet option the boot is seen to stall after printing
"intel_pstate: HWP enabled".
Here's a screenshot: http://i.imgur.com/cr5i72L.png
Searching around found me another report from a Yoga 260 owner with the same
issue. They've got a Skylake i5 whereas I've got a Skylake i7. A suggested
workaround was to use kernel parameter:
intel_pstate=no_hwp
This allowed boot of the debian-installer and this installed kernel but I
understand it disables many desirable power efficiency features.
Thanks,
Andy
PS reportbug has included kernel logs that show many errors, but I do not
believe these are relevant to this report. They are triggered by PID 994 which
is Xorg and seem to occur when the screen resolution is changed. I'll report
that separately.
