sparc64 / bbc_i2c.c

[J.J. Green]

Hi all

I got bitten by this problem on sparc64 (a blade 1000)

  http://ubuntuforums.org/showthread.php?t=297474

summary :

  modprobe bbc

runs kenvctrld which uses 100% of a CPU for 5 seconds,
then 0% for 5 seconds, then 100% .. and so on. The author
cited above suggests removing the line 

  remove_wait_queue(&bp->wq, &wait);

in the function 

  static int wait_for_pin(struct bbc_i2c_bus *bp, u8 *status)

Is there a better way?

I can test patches if that would be helpful.

Cheers

Jim
