Hi all!
When I read cdroms with fbsd 5.0, the following message appears in the console very often (it seems to happen with every cdrom I try):
acd0: READ_BIG command timeout - resetting ata0: resetting devices .. done
It is repeated indefinitely and I can't kill -9 the process that is trying to read the cdrom.
"umount -f /cdrom" also gets stuck and doesn't write any error messages.
The driver in use is cd9660: RockRidge Extension.
I have to reboot to have access to the cdrom drive again. And besides, the shutdown process does not end every time when the system is in this state.
Is there a means to have access to the cdrom drive again without rebooting? I have not seen any bug report for this problem; am I right?
Just wanted to report that I fixed this problem by adding:
hw.ata.atapi_dma="1" # Run the CD-ROM/DVD in DMA mode
to /boot/loader.conf. The system was trying to access the drive using PIO4 rather than DMA and crapping out. I got the idea from another thread today with the subject "playing mp3's and burning a cd". Just an FYI.
