| Hi all,
After having fixed all bugs in our driver (hopefully...) we have not seen any crashes for over 14 days. Now we hit another crash. However it doesn't look like our driver is involved at all. From what I read this is lookupd crashing the kernel? Does anyone have a clue what this chain reaction could be causing? I have a core dump from this crash.
