So many other things don't work automatically for me in 2.6 that one little echo for cdc_acm is a little thing. Besides, hotplug doesn't work either - something about the arguments to /sbin/hotplug has changed since 2.4 and I am in no rush to install a new version. Thanks for the modem fix.

Sorry, but if you want hotplug to work in 2.6, you will have to install a new version due to some changes to the network arguments, and due to a bug in the older versions of the scripts. thanks, greg k-h ^ permalink raw reply [flat|nested] 13+ messages in thread

Try the latest :) But that oops should have nothing to do with the scripts, that's a kernel oops that I could never duplicate :( thanks, greg k-h ^ permalink raw reply [flat|nested] 13+ messages in thread

Whenever I run the 2.6 kernel resolved oops through the user space ksymoops, it points to a different part of the kernel, leading me to suspect that i shouldn't be doing that. Is that right? Also I use modules a lot, will that affect this? I'd like to get this fixed. Any instructions / patches would be helpful. ^ permalink raw reply [flat|nested] 13+ messages in thread
