[BUG] 2.5.27 floppy driver

[BUG] 2.5.27 floppy driver

[Nico Schottelius]

[-- Attachment #1.1: Type: text/plain, Size: 485 bytes --]

Sorry to disturb again:
The floppy driver is broken in this kernel, too.
Reading/writing lets the accessing program just 'hang around'.

Luckily the floppy driver is happy and reports its problems to us.

See [hopefully] attached file floppyerr.

Yes, and it will stay broken unless somebody nice comes along and fixes 
it. I don't have a floppy, so...

is it impossible to use the one from .25 ?

You do. But as mentioned, it's broken. It was these VFS updates...

The latest vfs updates i've found are the ones in the 2.5.22
changelog...

Yes, the floppy driver is broken for quite a while now. It's a well-known 
problem.

I am wondering that I can't use it in .27, if vfs changes were in .22 and .24
worked, too.

        The last 2.5 series kernel that had the floppy driver working fine for 
me, was 2.5.7. I want to say it was in 2.5.13 that it was broken. But tread 
warily with anything that early in the tree. there's bound to be a number of 
things that were being broken back then. 2.5.7 was the last in which 
everything that I needed worked for me.

                                                        BL.
