PROBLEM:  (BCSM61SW3)    (Patch ID: OSF440-145)
********
This patch fixes an intermittent hang most commonly seen
on the DS10 workstation.  This hang occurs in the I2c code
where the timeout() system call is being used in a do-while busy loop
in routines wait_for_i2cfree() and wait_for_i2c_nointr().
