Comment 10 for bug 1453593

HP Elitebook 6930p, Intel graphics, with fully updated Ubuntu Wily and kernel 3.19.0-17 also freezes early in the boot. It appears to happen just as the low resolution display changes to higher resolution.

Booting in recovery mode results in low resolution display.

Kernel 3.19.0-16 is OK as is mainline 3.19.6
