Hi,
2013/9/5 Arend van Spriel <arend@xxxxxxxxxxxx>:
Since 3.11-rc4 I am seeing a problem with bcma on x64 (see attached
log). I
thought I misconfigured my setup, but just upgraded to 3.11 and I am
still
seeing the same issue. Did you have any reports like this?
Unfortunately I wasn't testing final 3.11 with x86_64, I'll give it a
try over the weekend.
I am bisecting. Will let you know when I find something.
Bisect points to:
fd4edf197544bae1c77d84bad354aa7ce1d08ce1 is the first bad commit

bcma: fix handling of big addrl
The return value of bcma_erom_get_addr_desc() is a unsigned value
and it
could wrap around in the two complement writing. This happens for one
core in the BCM4708 SoC.

It is probably caused by using IS_ERR_VALUE() macro which does a
unsigned long cast, which gives different results on 64-bit platform.
This patch was submitted upstream yesterday by Dave for 3.12-rc1.

Hi Arend,
Thanks for spotting this. This commit is not in final 3.11, otherwise
I would have suspected it before.
Yeah. It will need to be fixed for 3.12 after the merge window.
Could you please try the attached patch.
Just tried my own patch, which essentially does the same (not using a
macro).
So you may add
Acked-by: or Tested-by: Arend van Spriel <arend@xxxxxxxxxxxx>
Whatever you think is most appropriate.
Regards,
Arend
