While installing Linux 2.0.0, I found the following, well, let's name it "bug":
I am running linux on a 486-66 PC box with VLB/EISA busses and a AHA2742T as
As you know, EISA supports two kinds of interrupts: level and edge triggered.
Level triggered interrupts allow sharing of IRQs and that is what the driver
is configured for by default. So far, so nice.
However, some boards (the old ones - like mine) have problems with this kind
of interrupt. So, after the IRQ mode has changed and the SCSI Bus has been
scanned, the systems fails with an ISR error. Bad!
The problem was how to install Linux with a kernel that permanently traps.
Once again I realized that there is no way to install a PC without having
another one next door. So, things ran fine after one day. However, since I do
know that I am not the only one having this kind of trouble, I would suggest
to change the default behaviour of the driver. If you really do share one IRQ
within your PC, then it should be easy to change things back after
