On platforms that run the bcm56xxd daemon, the polling time that the system waits for I2C bus transactions to complete runs too long. On systems with I2C bus issues, this can lead to bcm56xxd core files, because the bcm56xxd daemon doesn't reset the watchdog so the watchdog timer kills the process.
bcm56xxd process may core and restart. That typically resets the I2C bus, which resolves any issues.
This is an issue only when there is a stuck I2C bus, which occurs rarely.
None. Typically, the issue resolves itself.
The number of times the bcm56xxd process polls for an I2C bus transaction to complete is reduced to prevent bcm56xxd core files.
