Same problem here:

[    58.504] Fatal server error:
[    58.504] xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call

hw/xfree86/os-support/linux/lnx_init.c:


 62 static void
 63 switch_to(int vt, const char *from)
 64 {
 65     if (ioctl(xf86Info.consoleFd, VT_ACTIVATE, vt) < 0)
 66         FatalError("%s: VT_ACTIVATE failed: %s\n", from, strerror(errno));
 67 
 68     if (ioctl(xf86Info.consoleFd, VT_WAITACTIVE, vt) < 0)
 69         FatalError("%s: VT_WAITACTIVE failed: %s\n", from, strerror(errno));
 70 }

lines 68 is interrupt by signal ... and ioctl(VT_WAITACTIVE) return -1, errno == EINTR.
Xserver must retry operation again! See kernel sources, VT_WAITACTIVE ioctl() handler
does wait interruptable() and can return EINTR.

Patch like this might help:
