Crash in e1000e, 3.3.8+ (tainted)
Subsystems (2)
We have a somewhat reproducible crash using a 6-port NIC with 3.3.8+ kernel. This kernel is tainted with a proprietary module, but the module is not in use.
The rx-all and related patches that were later accepted upstream have been applied to this kernel.
It seems that buffer_info is NULL in the code below?

I believe this has already been fixed in 3.4 via commit bb9e44d0. Please try patching your kernel with that and let us know so we can have it back-ported to stable.

Subject: [E1000-devel] Crash in e1000e, 3.3.8+ (tainted)We have a somewhat reproducible crash using a 6-port NIC with 3.3.8+ kernel. This kernel is tainted with a proprietary module, but the module is not in use.
The rx-all and related patches that were later accepted upstream have been applied to this kernel.
It seems that
buffer_infois NULL in the code below?

Ben,
This looks familiar to me, I believe this is due to race between adapter reset and e1000_close. Let me check if we have fix upstream or not.

Ben,
This looks familiar to me, I believe this is due to race between adapter reset and
e1000_close. Let me check if we have fix upstream or not.
I'm testing Bruce Allen's suggestion now: bb9e44d0 (from 3.4).
It applies with fuzz to my 3.3.8+ tree.
So far, so good...but need to do some more reboots to be sure.
Thanks,
Ben
