Hi,

   Sorry for bothering you  again - I will appreciate your opinion advise guidance. 
I'm trying to use the MPC I2C controller to generate I2C transactions,I use linux kernel,which config is CONFIG_UCODE_PATCH=y,CONFIG_I2C=y,CONFIG_I2C_ALGO8XX=y,CONFIG_I2C_CHARDEV=y,CONFIG_I2C_PROC=y.

I use XPC823EZT75B2 cpu,but when I start up the board,I found I2c driver huang the cpu.

What is your interpretation of entries I found in the log buf with regards to I2C driver ?
which is sleep,I2c can't tranimit,which can not interrupte.That is why?
Best thanks to you!
