Some older flash cards dont correctly decode master/slave. All anyone can actually do with them is keep a blacklist of "has no slave" cards. That was what I thought so I went looking for a blacklist and failed to find one. I did however find the following comment in ide-probe.c just above the function drive_is_flashcard(): CompactFlash cards and their brethern (sic) pretend to be removable hard disks, except: (1) they never have a slave unit, and (2) they don't have doorlock mechanisms. As my card is showing up in the log as "SunDisk SDP3B-85, CFA DISK drive" it must be being detected as a Compact Flash card (otherwise ide-probe.c would have printed "ATA DISK drive") and hence according to note (1) above there should be no reason to check for a slave drive. Now people use CF->IDE adapters its no longer true 8( If a PCMCIA/CF storage card is plugged into an IDE port it will presumably show up as an IDE device on a std controller whereas if it is plugged into a PCMCIA or CF port it will use the ide-cs driver. If this is the case, would it be possible for the latter driver to have code to disable probing for slave devices? Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
