Precisely as expected from our past work, 2.6.7-rc2, even with the not-substantive ata_check_bmdma rewording, still can't cope with expecting no data for a CDB. A CDB that actually copies is ok only if I lie to say I expect data: $ # "INQUIRY" for up to zero bytes $ sudo plscsi -i 0x12 -x "12 00:00:00 00 00" $ Honesty receives its expected penalty: $ sudo plscsi -x "12 00:00:00 00 00" $ Message from syslogd@patibmrh9 at Sun May 30 09:18:00 2004 ... patibmrh9 kernel: Disabling IRQ #18 $ Pat LaVarre
