Andre,
Above is the patch that will fix the bug that when a user issue the command:
cat /proc/ide/hda/identify
the message "hda: bad special flag 0x03" gets written to the system log. This will happen because the .config file that RedHat uses to create the kernel image has the flag CONFIG_BLK_DEV_IDECD=m. Thus in ide.c code, it won't call ide_cdrom_reinit(). So for CDROM the special flag is left as 0x03.
The solution is to set the special flags to 0 when it is discovered as cdrom in ide-probe.c.
Let me know if you have any question.
Thanks,
