Hmmmm, semi-repeatable failures to boot all the way up to
a GUI-based login?
My first guess might be:
- Maybe your graphics subsystem couldn't be initialized.
Maybe your adapter has problems after a warm boot?
Maybe driver not allowing enough time for initialization?
Maybe compare output from "lsmod" for each case?
See previous suggestions about /var/log/Xorg.0.log and friends.
Another (rather less probable) shot-in-the-dark guess:
- Maybe GRUB is intermittently loading the wrong kernel or
handing it the wrong commandline.
Are we sure you're running the same kernel in both situations?
Maybe compare output from "uname -a" and "cat /proc/cmdline"
for each case?
I only mention that because the sort-of-cyclic nature you
described made me think it's just barely possible you're
enjoying some variant of this little bit of GRUB hell:
