Description Len Lawrence 2015-02-13 18:20:13 CET

Description of problem:
Customized install of Classic DVD iso from USB drive booted under UEFI Only. The install completed without any problems. USB drive removed, reboot. The system hung after Loading initial ramdisk; would only proceed if the USB device was plugged in again within a 10 second timeout.

Layout of system:
hd0 = 512 GB ssd : GPT partitions
1 = /boot/EFI 2 = swap 3 = /

[root@localhost grub2]# gdisk -l /dev/sda
GPT fdisk (gdisk) version 0.8.10

Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present

Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 1000215216 sectors, 476.9 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 817759E9-DAA1-4E14-AC2C-E24CA7D92CDC
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 1000215182
Partitions will be aligned on 2048-sector boundaries
Total free space is 98925 sectors (48.3 MiB)

Number Start (sector) End (sector) Size Code Name
1 2048 1050623 512.0 MiB 8300
2 982632448 1000118271 8.3 GiB 8300
3 1050624 982632447 468.1 GiB 8300

Note that gdisk reports all partitions as ext4 but at reinstall the partition table
seems to be OK, i.e. Windows, ext4, swap.

Version-Release number of selected component (if applicable):
Mageia 5 beta 3

How reproducible:
Tried full installation five times - same behaviour

Steps to Reproduce:
1. Install Cauldron from EFI-prepared USB device under UEFI-only
2. Reboot
3. Wait

Reproducible:

check if /etc/fstab contains any reference to the install media

CC: (none) => tmb

Comment 3 Len Lawrence 2015-02-13 19:12:40 CET

That was the problem.  Deleted the reference from fstab and no more problem.
Bug closed.  Thanks.

Comment 4 Thomas Backlund 2015-02-13 19:17:20 CET

Yeah, so the installer trying to be helpful with adding windows partitions hurts us here as it sees the fat32 usb stick and adds it to fstab... That we need to fix

Comment 5 Thierry Vignaud 2015-02-14 14:13:49 CET

Well fs::mount_points::suggest_mount_points_always() do try to filter removable media.

Can you attach your /root/drakx/report.bug.xz?
I'm especially interested in the "win parts:" line

Comment 7 Len Lawrence 2015-02-14 16:47:27 CET

Removed the grub.cfg attachment and added an extract from around the "win parts:" line.  If you need the whole file let me know.

Comment 8 olivier charles 2015-02-14 17:30:54 CET

That affects Mageia4 x64 as well (EFI install from USB with classic DVD x64).

An entry for the usb stick is added in /etc/fstab during installation.

setting as blocker (we had same issue on previous version without uefi, now resolved)

Comment 10 Thierry Vignaud 2015-02-18 10:28:37 CET

Actually I think it's a side effect of bug #14435 which broke detecting USB devices
