Hmmm, so then I must apologize, since it was my fault to not check the newest state. We use uClinux 2.6.23 from May 2007. Ok, I will do some testing with the newest one linux 2.6.31 and try to play with IRQF_DISABLED. Thank you for information. BTW, is there any link, that explains new interrupt handling?

Yes, you are also right, finally with the new arguments about Linux our management decided to create completelly new HDL components, that will fit all the needs. In our case we will use FIFO long enough to catch data until Linux is ready to read it. SG DMA is also possible, but experiences shows to HDL designers, that using proved components is allways much better option. Thank you,
