I applied the patch and (bingo!) the kernel now boots without panic. the picture also changed a bit, the CD-ROM is listed now at 20.0MB/s. but when I try to mount a disc I get an error: boca# mount /dev/cd0c /mnt mount: Input/output error and the syslog shows: Nov 4 19:50:03 boca /kernel: (cd0:ahc1:0:3:0): parity error during Command phase.
