Hello Evgeny Novikov, I installed ldv-console and visualizer successfully, but when verifying the cdrom driver by command: LDV_VIEW=y LDV_DEBUG=100 ldv-manager tag=current "envs=linux-2.6.36.tar.bz2" kernel_driver=1 "drivers=drivers/cdrom" "rule_models=32_7 32_1" Then, upload to the database, I got the "failed before RI" results. The most strange thing is that the warnings/errors seemed as the same to the other success verifying process ,such as the usb kernel driver. I attached both the outputs by files "cdrom.log", and "usb.log". and the usb verification results is: So , what should be done to solve the problem? Thank you in advance! -- Best Regards, MA Lele -------------- next part -------------- An HTML attachment was scrubbed...
