Kernel built configuration

Hi everyone,

for me, rc6 worked with 3.8.2 and prior but is broken in 3.8.3.
With previous versions I used bitmask 7,
with 3.8.3 all bitmasks (except 0) hang the machine immediately after kernel load; hard reset needed.

Additional information attached.

Can you please bisect where this regression has been introduced exactly?

git checkout f49b7242e6220ace73138ccae5caa85c59499ed7
make; reboot
--> Seems fine

git checkout 2a9810441fcc26cf3f006f015f8a62094fe57a90
make; reboot
--> Problem described above

2a9810441fcc26cf3f006f015f8a62094fe57a90 will be reverted in stable, it blew up in way more places than just on your machine. So your regression should be fixed in the next 3.8.x release.

Thanks for reporting this issue and please reopen if it's again broken.
