I've been seeing radeon related crashes upon boot on my laptop for a while |
2 |
now, but I could just recently capture this Oops, which can be related. If |
3 |
the machine hard-locks on boot, I can capture no messages. It looks, that |
4 |
most of the time it can regenerate from that state somehow and continues |
5 |
on without any problems. There was a kernel version months before, for |
6 |
which boot resulted in a hard-lock each time. It happens once in every |
7 |
couple of startups only. |
8 |
|
9 |
It's a null pointer dereference. Where should I report that? |

I'm still having early-boot intel-iommu traces on my other machine, but |
56 |
without any symptoms. Might be related to a 3ware card, fully functioning, |
57 |
housing the system - therefore I cannot verify... |
