sci spurious irq on sh7203

[Federico Fuga <fuga@studiofuga.com>]

Hi All,

I am working on a sh7203 based board, running the linux-sh kernel 2.6.37 [3c0eee3fe6a3a1c745379547c7e7c904aa64f6d5]
I am experiencing a bug when using the sci0 as a console.
The serial port is working as expected, except when more than a certain number of characters are sent to the console; in this case, the kernels traps many spurious interrupts that triggers the __report_bad_irq() function and disables the IRQ vector 192.
I append a snapshot of the console output.
As you can see, I modified some kernel sources to output the status of some register - also not related to SCI.
I modified the sh_sci.c source to trigger an output of the irq registers when no irq routine is serviced - basically a flag that change state when sci_tx_interrupt or similar function are called from inside sci_mpxed_interrupt.
So I noted that the error is triggered when 

ssr_status\0000060 
scr_status\0000078 
err_enabled\0000040

The strange thing is that the irq is triggered for TEND flag and TX FIFO Empty even if TIE is disabled.
I was investigating both tx and rx interrupt routines, but I see nothing strange happening. But it seems something related to Receiving too many characters (a stream of 15 bytes do not triggers the problem; 16+ bytes almost always triggers the problem), since Sending seems to work fine.
I also tried to update sh-sci.c/h and some other header file (in arch/... and include/linux/...) to the latest version, and compile, but the problem persists. 
Actually I cannot test any other serial port for this problem, but I hope I can make this test soon.
Thank you in advance.

best regards
