KSZ8895 Switch-Circuit Problem
You should read the datasheet for the strapping and configuration pin options.  I'm not sure whether they all float to a valid configuration (particularly SCONF0, SCONF1, PS0, PS1 and obviously MDIXDIS which is probalby the source of your trouble).

Also, try using a crossover cable to connect to the second switch, you might have auto-MDIX disabled with the default strapping options.

I also have a vague recollection that you have to supply reset logic, the internal reset is not reliable with all all power supply rail ramping possibilities.
