Hi Kari
This rings a bell in my mind. There is(was?) a line early in the irq routine
where i2cmod(?) is disabled(there is a comment that states that this is
due to some chip errata).
First a commeted this line and my I2C was starting to work. Later
I moved it to someplace directly after IRQ context and now my I2C is
working fine. Do you know what this "chip errata" referes to? I could
not find any reference to this in any Motorola doc.
If you want, I can send you my version of the i2c-algo-8xx.c driver(I am at
home
now and don't have access to the driver now)
Regards
Joakim Tjernlund
PS.
I am also using motorola I2C microcode patch
