[Linux-parport] The Intel parport bug

[Leopold Palomo-Avellaneda]

Package: linux-image-2.6
Severity: normal
Tags: patch

Hi,

there's a bug in the parport module that have been reported (in another 
places) some time ago [1]. Also, this bug was reported at Redhat [2], but 
nobody follow the report and it was closed.

As Adam baked said [1] :

<quote>
A long time ago (~ 10 years), Intel produced a chipset that 
included broken EPP support. The Linux parport driver was written to detect 
such a chipset and disable EPP support on it. Unfortunately the test that was 
written gives false positives for many current chipsets and no-one seems to 
know exactly what the problem hardware was, let alone have a sample of it to 
see if a better test can be written. After such a long time it is probably 
appropriate to just remove the test (on average it does more harm than good) 
however you are correct in asserting the driver is unmaintained so no-one is 
bothering to fix it.

I have applied the patch to the standard debian kernel and it compiles and 
runs perfectly. Applied to some Dell hardware, now the EPP mode is detected 
and, after some initial tests it's working.

I don't have any hope that it would be solved in the linux kernel, but at 
least in the debian kernel it could be applied.

Please, apply the patch.

Best regards,

Leo
