I hate jumping in like this out of the blue, but time is not on my side atm with a lot going on. I have a problem with some devices disappearing on various versions of FreeBSD and machines (laptops, workstations/servers). Umass are the norm, with the message occurring most on usb sticks and sd cards. Big problem atm is that my file server has a failed disk in the raid, and I've tried replacing it with a new drive (twice now), and both times it begins to resilver and then it is "REMOVED". If I online it again, it goes for about 10mins then REMOVED again. Dmesg shows that the device is removed from the devfs with a passdevgonecb/lost device message. This apparently occurs right at boot too, as it shows amongst the usual scrolling during boot. I had a chat with someone and they mentioned the cable and/or controller could be the issue. Could anyone add any insight or tests I could do? I'm not exactly claim to be an expert at zfs, so maybe something might need addressing there too. I'd particularly appreciate a means of testing the controller. ATM the main theory is to replace the board - not a happy thought! :/ TIA
