Then, over time, thigns will become :more or less stable as the work progresses. Some days will be good :tree days, others bad. So long as I can boot my laptop with -current :to do pccard work (which means it must last 15 minutes of light usage, :ideally more), then it meets my lower bounds of acceptible. It would :be nice if I could also build kernels and such on my laptop during :that time as well, but that isn't as critical to me since I can reboot :with the older kernel. There's some pain, but on the whole it would :be workable if I can do these things. : :I know that it is hard, but can you characterize the level of :instability that I'd see on a regular basis? Where in the continum of :"we talking uptimes of 1 minute or less" to "don't put this into :production" do you see things most of the time? : :Warner Hmm. I think from the point of view of pccard development you will be in good shape. I can't really guess what the level of instability will be, but I think if we test things enough before committing (i.e. the machine has to survive a 'make' of the kernel) that it should be good enough to not intefere too much with your pccard work. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
