Unfortunately, that is not enough to get DVD burning working again. This is the error that growisofs is getting: ioctl(6, SG_IO, {'S', SG_DXFER_TO_DEV, cmd[10]=[2a, 00, 00, 00, 03, 10, 00, 00, 10, 00], mx_sb_len=64, iovec_count=0, dxfer_len=32768, timeout=60000, flags=0x3, data[32768]=["\360R\360\314Wt\277\241\36.\347\356L$\201]\210\372_~]I\213\366\253SV\2\372\356\312\257"...], status=02, masked_status=01, sb[0]=[], host_status=0, driver_status=0, resid=32768, duration=0, info=0x1}) = 0 write(2, ":-( unable to WRITE@LBA=310h: ", 30) = 30 It looks like the sense buffer is not filled in. In a successfully run of growisfs under 2.6.24.2 the sense code is "LONG WRITE IN PROGRESS". I also see that resid always equals dxfer_len even when the transfer was successful, although growisofs does not seem to care. With 2.6.24.2 resid is only non-zero when a sense error occurred.
