s3c6410 and DM9000 problem

[Vitaliy Stolyarov <svitaliy77@xxxxxxx>]

Hi all,

I am working with s3c6410 based board (with linux 2.6.28.6). I am using DM9000E chip as ethernet connected to 16 bit data bus (SROM_BC1).  

In u-boot ethernet works fine. 
But in the linux kernel (with the same SROM controller settings ) ethernet works unstable and very strange:

In interrupt handler (dm9000_interrupt) received interrupt status has the value which not documented  in DM9000 manual:
	int_status = 0xFE.

After receiving interrupt with status (0xFE) I can't yet ping my board from host.
But I can ping host from board with some delay, and only after this I can ping my board from host.

If anybody has circuitry of DM9000 connected to S3c6410 and working DM9000 software driver, please help me.

Thank you,
Vitaliy Stolyarov.
