I am really out of ideas now. I think that we have tried every qu= irk that Linux may use and nothing works... One idea is trying the previous patches in combinations... I would like to see SCSI debug messages that are produced during the origin= al probing. The problem with getting them is that the only way to get them is= to enable debug messages for all devices. And that means noise from ada0 and ada1. Maybe you could the following: 1. stop syslogd, so that the kernel log is not written to disk causing the positive feedback loop 1a. alternatively, boot to single user mode and do things there 2. camcontrol debug -c -p -I -P all 3. plug the device 4. wait until CAM messages settle down 5. camcontrol debug off 6. check the captured messages in dmesg output --=20 You are receiving this mail because: You are the assignee for the bug.=
