| |
Hi, everyone,
Starting with Linux 5.7-rc1, my Arrandale (Core i3-380M) laptop is completely unbootable (the last messages on screen are GRUB's loading kernel/initramfs). I was hoping someone would have noticed it before 5.7-rc2 had been tagged, but alas. Anyway, I bisected it down to commit 1567c3e3467cddeb019a7b53ec632f834b6a9239 (x86, sched: Add support for frequency invariance). After reverting it, the machine boots again, obviously.
Let me know if you need any further info in order to fix this issue.
Complete bisection log follows.
