Re: [PATCHSET] Linux 2.4.19-pre7-jam1

Well the proper solution is for me to finish the "ide-flash" subdriver.
As CFA devices have special error transformations and decodes, as will any
SDA device.

Proper error path in the driver ... hmmm, I have a discription and batted
it around and more people understand the problem now.  The issue becomes
in full disclosure and not producing a mass panic.  I would like to have a
solution complete before "wolf" and nothing to kill the beast in sight.

Cheers,
