I've pawed through the mail archives, but didn't see any clear pointers on this one, so here goes: I have a NEC 272 CD ROM drive, that probes at boot, and works well. But I've noticed two set of symptoms: - my console gets clogged with '/kernel: wcd0: cannot read audio disc' messages. What is directing the kernel to try, when I'm not running xcdplayer, or the like? - Inevitably, I will see this after a couple of hours of using the drive: Jun 5 12:52:06 aobrien /kernel: atapi1.0: unknown phase Jun 5 12:52:06 aobrien /kernel: wcd0: i/o error, status=0, error=1 after which the drive is not accessable via software, as the incurring process blocks forwever, and cannot be KILLed. Is there a way of 'unwedging' the drive, so I can make further use of it? I suppose my biggest problem, is that this all begins a death spiral, where suddenly various processes hang, so badly that I cannot even log in remotely to straighten things out. I've been using FreeBSD for a couple of years now, and this is the first time I've had userland processes wedge a machine to the point of forcing a complete restart. Does anyone have any observations on this whole mess?
