Package: cdrom Severity: important Tags: d-i Dear Maintainer,
Debian installer from official testing build for 2017-07-10 from http://cdimage.debian.org/cdimage/weekly-builds/amd64/jigdo-dvd/debian-testing-amd64-DVD-1.jigdo fails on "detect cdrom" stage. I write the image to my SATA drive as follows: dd if=debian-testing-amd64-DVD-1.iso of=/dev/sdb bs=4M; sync The reason is that installation media cannot be mounted, as verified from Alt+F2 console: mount /dev/sdb1 /mnt mount: mounting /dev/sdb1 on /mnt failed: Invalid argument But when I issue modprobe isofs mounting works fine, and the installation resumes after I repeat cdrom detection. At https://www.debian.org/releases/sarge/debian-installer/ in the section "SATA driver can block access to CD drive in installations from CD" it is written that "isofs" module is necessary in order that sata driver will let access the device. As it turns out, usb driver lets to access the device without "isofs" module. Adding "modules=isofs" to kernel boot parameters gives nothing. So, please make debian installer load this module automatically at an early stage. (Installing from SATA drive is a neccessity. No usb flash drive.) -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
