Sorry, the bug report is confusing. It's actually two bugs, the first being |
| 13 |
a miscompiled stage2 causing an error when running grub-install and making |
| 14 |
the system unbootable. I fixed that back in Sept. The second bug is a |
| 15 |
continuous boot loop that only seems to manifest on certain machines or |
| 16 |
configurations. This is the one I'm having trouble with. I should have |
| 17 |
opened a new report for it, but at the time I thought it was due to fallout |
| 18 |
from the first patch. |

The biggest problem is that I can't reproduce it on either of my systems, so |
| 21 |
I have no way of narrowing it down. FWIW, I did a comparison of /boot/grub/* |
| 22 |
from a broken system and my own and they are byte-for-byte identical. |
