But that requires manual user intervention. And it has been working without any manual user intervention before. That is why I called it regression. I just try to draw attention to simple (but very nasty for users) problem in udev. This quotation removed too much from my original post to reduce the problem to simple "how to reread partition table". > Is there really no way to get a media change notification from ZIP or > JAZ drives? If anyone knows please tell me - I will put it into supermount ... AFAIK in case of SCSI this is impossible simply by virtue of protocol - SCSI device is not initiator. So you need something to poll device for status. That is usually done on device open except in this case you can't open because you do not yet have handle. thank you -andrey - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
