Entirely by accident, I updated my ancient version of grub. Once I found |
| 2 |
out I said to myself that it would be better to update the boot stages |
| 3 |
but this is what happens: |
| 4 |
|
| 5 |
~ # grub |
| 6 |
grub: asmstub.c:215: grub_stage2: Assertion `simstack_alloc_base != |
| 7 |
((void *) -1)' failed. |
| 8 |
Aborted |
| 9 |
|
| 10 |
I hadn't run grub in AGES, so I can't say what/when it broke. The good |
| 11 |
news is the machine still boots but I'm not in a reliable condition. |
