If I wait a long time to enter the > password all is well. I had problems with late reset of usb devices (with connected usb keyboard). When I start to enter passphrase (in initramfs), usb kernel module resets usb devices (perhaps just initialization) and usually it cause lost of some entered characters. Waiting few seconds helps - maybe this is the similar case or just problem with another hw interfering (like gpu). To debug such issues - boot kernel, intramfs (dracut or whatever it is) with full debug to console, check what is logged immediately before it happens. (If it is too quick, just use some camera and record screen or log it to serial console.) With passphrase entered in late init where things run in parallel (like systemd these days) even more magic can happen;-) Milan _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
