Could you open a bug on bugzilla and attach dmesg and
/sys/kernel/debug/dri/0/i915_error_state, so we could look into it further?

ose patches fix the crash you are having, but I am wondering why the crash =
happened in the first place. E.g., we should not get to the situation where=
 region is NULL under normal cases.<br>

<br>From what it looks like, it could happen when GPU was hung for example.=
