Hi all, I ran guix pull and system reconfigure today, updating my kernel to
5.19.12. On rebooting I was unable to get much past the bootloader before
the screen started flashing. Aparrently there's a regression in 5.19.12
that couses this issue in some intel laptops. Because guix is guix I just
rolled back for now.

This regression was fixed in the 5.19.13 stable release.

shows the effect on someone elses laptop (not guix). They say that 5.19.11
works fine and while I haven't checked that myself, I can say 5.19.9 works
fine.

Thanks for the report. I was wondering if it was also happening with the
linux-libre kernel. The 5.19 kernel has been updated to 5.19.14, so all
should be good now.

Of course let us know if it comes back with the newer kernel version.
