Apparently I had for whatever reasons EDD turned off till recently. This is 2.6.27-rc5 just in case. In 2006 I fixed ghost devices due to buggy BIOS: http://marc.info/?l=linux-kernel&m=114087765422490&w=2 Later edd.S has been rewritten in C, and apparently this patch has been lost: {pts/1}% ls /sys/firmware/edd int13_dev80/ int13_dev84/ int13_dev88/ int13_dev8c/ int13_dev81/ int13_dev85/ int13_dev89/ int13_dev8d/ int13_dev82/ int13_dev86/ int13_dev8a/ int13_dev8e/ int13_dev83/ int13_dev87/ int13_dev8b/ int13_dev8f/ But I have just a single disk. This is the same system BTW. Unfortunately I do not speak asm language of C; if somebody could provide equivalent fix for current edd.c, I am more than ready to test it.
