Tried with i2c-core, i2c-proc, i2c-viapro and w83781d, with only w83781d
cycling. I noticed that the "free" memory as reported by top would
decrease almost to 0. However it would NOT generate a memory shortage.
If I run Firefox at this point, it'll get all the memory it needs (and I
disabled swap for the test). So I don't think I am able to reproduce
what you described.
Can you possibly try with each of the three modules (lm93, eeprom,
pcf8574) individually and see if all cause the trouble, or only one of
How much memory do you have on your system?

This would indeed be very welcome :)
