This might add more points to the Marcel' note = about > some static relocation table processed early. I built a kernel off of revision 286315 and got this: eris% objdump -R kernel | grep FPTR64LSB | wc -l 5377 We only reserve room for 4096 relocations, so we=E2=80=99re over as it is. A kernel off of revision 286316 gave me this: eris% objdump -R kernel | grep FPTR64LSB | wc -l 5377 Same. Odd, but ok. It=E2=80=99s possible that the memory layout changed such that we now scribble over something that=E2=80=99s important. To be sure: Anton can you apply the following patch and tell me if it makes a difference. It doubles the space we set aside for relocations.
