Having said that, I'm currently playing with nested interrupts - let's see how that checks out... :-)Do several consecutively, non nested, interrupts (e.g. priodical timer) work for you?
Yes those are working. I once saw issues with nested(!) Timer/NIC interrupts, but I rather suspece issues with the tricky EXL/IE/IMASK maniplation code which is involved when allowing for nested interrupts. I don't know whether Linux does that, actually.
