From: Johann Felix Soden <johfel@xxxxxxxxxxxxxxxxxxxxx> If the slot is already occupied, there should be written 0xff to idx[i]. In the ongoing code and in this case there are no writings to idx[i], so garbage stays in idx. The kernel get into a endless loop printing: : I/O resource 0x0-0x0 not free. Trying to free nonexistent resource <0000000000000000-0000000000000000> Trying to free nonexistent resource <0000000000000000-0000000000000000> This patch solves http://article.gmane.org/gmane.linux.ide/28810 .
