I am using qemu. Here are GOLDFISH related .config values: CONFIG_GOLDFISH=y # CONFIG_X86_GOLDFISH is not set CONFIG_KEYBOARD_GOLDFISH_EVENTS=y CONFIG_GOLDFISH_TTY=y CONFIG_BATTERY_GOLDFISH=y CONFIG_FB_GOLDFISH=y CONFIG_MMC_GOLDFISH=y CONFIG_GOLDFISH_AUDIO=y CONFIG_MTD_GOLDFISH_NAND=y CONFIG_GOLDFISH_BUS=y CONFIG_GOLDFISH_PIPE=y Is it a known issue? How can it be fixed? Thanks _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
