Hi,
With 3.0.1 now and all options compiled in and threadirqs removed, I get the
same error this user is seeing:

Hello Lin,
I missed your mail (sender IP is in a CIDR blacklist), disabled & whitelisted
for now:
http://marc.info/?l=linux-kernel&m=131567477126674&w=2
I've enabled this and I will post a new e-mail / output if it happens
again with debug enabled for SLAB.
Response to your e-mail:
Could you tell how to reproduce this?
Running a lot of processes at the same time (memory/cpu+i/o)
And would you please turn on more debug options to capture more info?
Yup, done now; however, I am using SLAB, not SLUB; so I've enabled:
-> [*] Debug slab memory allocations
-> [*] Memory leak debugging
-> [*] Debug VM
CONFIG_SLUB_DEBUG=y
CONFIG_SLUB_DEBUG_ON=y
CONFIG_DEBUG_VM=y
Please let me know if there are any other options you think would be useful
to enable or if this should be good, if it recurs again-- as noted above
I will post an update.
Justin.
