smbus or i2c or iic whichever name you want.

Think what happens when you try to read the serial SPD eeprom on the memory
and the read fails or the smbus locks up.  Basically random peculiar failures.

It depends but when pushing the boot failure rate down from 1 in 100 to 1 in 1000
this is the most common issue that crops up.

This is one of the reason my smbus read code has a timeout on it.
