Re: PCMCIA CD-ROM does not work

[Thom Borton <borton@phys.ethz.ch>]

Hello Marcelo

The problem seems to be one of those self-healing things that occur 
once in a while. I just tried 2.4.23-pre9 and the CD-ROM drive works 
again. Plug in the PCMCIA card, double beep, mount disk, read it, 
unmount, unplug card. A mysterious syslog message about a "bad 
special flag" that had always shown up has also disappeared.

Seems like someone has worked on it :-)

Anyways, thanks to all kernel developers,

Thom

P.S.: For those interested, the problem was about a PCMCIA CD-ROM on a 
Sony Vaio PCG-Z600NE that stopped working with 2.4.21/22.
