Bug Description
The udisks2 tests (https:/
This can be reproduced with these commands, which will operate on a virtual scsi_debug device (so they won't change any data on your system). But beware, this completely crashes and freezes your computer, so save all documents before!
sudo modprobe scsi_debug
sudo luksformat -t ext4 /dev/sda
sudo cryptsetup luksOpen /dev/sda treasure
Works fine up to here. But this causes the crash:
sudo mount /dev/mapper/
This is not hardware specific. It happens on real iron and in kvm, on i386 and amd64. I tested it with starting the current amd64 desktop image in kvm, switching to VT1 (so that I can see the kernel oops), and running above commands.
