Hi, readcd seems to send a command with a zero datalength, which is unusual: https://github.com/jobermayr/cdrtools/blob/master/readcd/readcd.c#L1034
It seems though this case should be supported by avoiding DMA when no SG list is provided. https://git.haiku-os.org/haiku/tree/src/add-ons/kernel/bus_managers/ata/ATAPIDevice.cpp#n38
Note:
See TracTickets
for help on using tickets.
Also KDL's on x86_gcc2h. Change platform to "All".
