[Intel-gfx] Screen blanking when copying files to USB/SD-Card ??

[Fabrice Delente]

Hello.

I have noticed this bug of the driver when I copy a big gob of data to
an USB/SD-Card mounted driver, with vfat filesystem: the screen turns
off, and nothing can turn it on again. I can ssh into the machine,
where everything is still running ok, so it's really a display
problem.

I can turn off the screen with xset dpms force off, it turns back on
again correctly; I can use xscreensaver too.

This is on a Gentoo laptop, with this chipset:

# lspci
00:02.0 VGA compatible controller: Intel Corporation Mobile
GM965/GL960 Integrated Graphics Controller (primary) (rev 03)

I have this in Xorg.0.log:

[    62.133] (II) LoadModule: "intel"
[    62.192] (II) Loading /usr/lib64/xorg/modules/drivers/intel_drv.so

I don't know if any other info in /var/log/Xorg.0.log is relevant.

In /var/log/messages, I found this dump:

I hope this problem can be solved.
