Hmm, so this means that problem is curable by software => if linux delayed accesses by something like usleep( 1000 ), it would work?

Once again, why is not I/O delay done by usleep( good constant )?

New PCI board would be completely useless for me, as Elf (main computer) has VLB build in, and Hobit (the second one) is 386DX/40, which has no hope for PCI :-). WEll, if I should throw all broken HW into thrash, I would end up with putting into thrash everything except good old Atari 800xe. And since you probably can not run linux on Atari 800xe, it would be end of linux.
I thought that linux is wonderfull thing because it can make old, slow computers do _a lot_ of work again.
