next in thread | raw e-mail | index | archive | help
I don't use the floppy drive in my laptop (an Inspiron 7500) often, so it was
only a few days ago that I discovered that my floppy drive is not being
properly recognized in 5.4R with the generic kernel. I put my test drive in
the system, and it turns out that the floppy wasn't working in 5.3R either.
If I disable ACPI the floppy drive is set up properly and works fine in 5.4R.
I'm now booting off my old (i.e. spare) production drive with 5.2.1R on it,
and the floppy is working fine. So some time after 5.2.1R something changed
that keeps the floppy from being set up correctly.
In 5.3 and 5.4, the drive controller is initially recognized and fdc0 appears
to attach to it, but when I looked at a verbose dmesg, it appeared that the
ACPI system is deciding that the drive isn't usable. As a result, there is
no /dev/fd0 device installed. Unfortunately, at the moment I'm booted from
5.2.1, so I can't include the dmesg from the 5.4R boot, but I do have a copy
of the dmesg from a 5.3R boot attached below, it seems to show that fdc0 is
set up, but not fd0.
The fdc(4) man page says I need "device fdc" and "device fd" in my kernel
config, but if I do that in 5.4R, I get an error message that says "device
fd" is not valid.
With that background, here are my questions:
1) Is there an easy way to get my floppy drive working in 5.4R without
disabling ACPI? I don't really want to track -stable, I prefer the security
branch, and either way, anything involving building a new world will take the
rest of the weekend on this system.
2) What do I lose by disabling ACPI? Under 4.x I had APM working with
suspend to disk working well, so is there any real reason to stick with ACPI
rather than going back to that?
3) Is this likely to be fixed in 6.0 when it is released? If it is, I'll
probably ignore it until then. Unfortunately, I have more urgent problems to
deal with this weekend and I'm not likely to have time to install my 6.0
beta3 CDs to find out.
Thanks for any info you can provide.
Below is a dmesg.boot from 5.3R.
Thanks,
- Bob
