Description

Loading i915kms on current master (g34c2e9) locks up my laptop hard, screen is black, no core dump, no nothing.

History

This happens to me as well. I can shut off the lappy with one push at the power button as usuall though, but screen is all black. Latest master, x86_64.

If the machine doesn't lock up completely you are likely seeing a different issue. It could be related to https://github.com/DragonFlyBSD/DPorts/issues/87

Thanks! The xrandr line in .xinitrc made it work for me again.

It would be interesting to know:
- what sort of hardware you are using (gpu / cpu / chipset model)
- if the machine locks up with only the i915kms module beeing loaded manually or with Xorg loading i915kms

It happens on kldloading the module, as the bug report subject says.

I have tested on a thinkpad x61t and a thinkpad t500,

T500:
vgapci0@pci0:0:2:0: class=0x030000 card=0x20e417aa chip=0x2a428086 rev=0x07 hdr=0x00
vendor = 'Intel Corporation'
device = 'Mobile 4 Series Chipset Integrated Graphics Controller'
class = display
subclass = VGA
vgapci1@pci0:0:2:1: class=0x038000 card=0x20e417aa chip=0x2a438086 rev=0x07 hdr=0x00
vendor = 'Intel Corporation'
device = 'Mobile 4 Series Chipset Integrated Graphics Controller'
class = display

for the x61t I know that it's either a X3100 GMA or a 950 GMA, but since I don't have that computer running right now, I can't check.

For me this does not happen anymore on current master. There are still issues on the t500 in that the callwheel is corrupted, but that is #2649.
