Lantiq vrx200 xDSL firmware recommendation thread

Did anyone notice the DSL uptime drift (or lack of it) with different firmwares?

I'm currently using the one provided by default and I had to multiply the uptime value by around 1,0235 to get the correct uptime, so I'd like to know if it's specific to the firmware version or a general issue with xDSL modem in SoC?
