Hi Everyone,
I would like to disable EISA and its probes during boot. I found the docs at https://www.kernel.org/doc/html/latest/driver-api/eisa.html, but it does not discuss how to disable EISA or the probes.
I also found https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1543919, where folks are wondering why EISA is enabled by default nowadays. And one person asks about a kernel option to disable it (like I am doing).
I'd like to add a boot param like eisa=0 or eisa=off, but I suspect it's not that easy. Looking at the three documented kernel parameters, they all enable EISA and probes.
How do I disable EISA and the probes?
Build a kernel without EISA in it at all? That's the simplest way as you must have some custom hardware that doesn't like this, so a custom-configuration seems like the best option. Did you try that and it did not work? What is the problem of EISA at boot anyway? thanks, greg k-h
