Hi Sergio,

Esi Juli@ seems to be a different beast than most other ice1724-based 
cards. I am working on the driver, it will take a number of changes to 
the generic ice1724 driver due to presumably different clocking scheme.

The ice1724 midi driver has a bug causing kernel hang when opening the 
device. It has been reported, and Takashi has provided an experimental 


It would be great if you were able to test the patch. The midi device 
should work (hopefully) using the existing driver for Juli at .

Thanks a lot,
