We also see this on the release branch for 64: https://logs.chromium.org/v/?s=chromeos%2Fbb%2Fchromeos_release%2Fveyron_mickey-release_release-R64-10176.B%2F22%2F%2B%2Frecipes%2Fsteps%2FArchive%2F0%2Fstdout And this happened to Soraka on 10225: https://luci-milo.appspot.com/buildbot/chromeos/soraka-release/707 Gwendal, given this seems to be dying around the filesystem stuff is this something in your jurisdiction? If not please feel free to reassign. We really need to fix this as if it happens on releases it means we will be skipping boards when it does.

The factory shim is following same process as build_image so I'm not sure what may go wrong...

does this only fail on devices with cros_embedded set? (b/72749926)
Apr 25 2018,
#6: no, elm, veyron_minnie do not have cros_embedded set.

INFO : Creating FS for partition 12 with format vfat. The build script did create EFI (12) before starting to mount. And the message indicates a "sudo mkfs.vfat" should be called after that, with a mount (based on loop) then umount. In kernel source, the bogus number means reserved sectors = 0, but mkfs.vfat should create at least 1 (for FAT16 - which is the default selected value for our EFI partitions). I wonder if there's some cache/sync/flush issue, or mount_gpt_image has some bug, or the calculation of offset in mk_fs has overflow.
Apr 26 2018,
well, $(()) seems supporting 64 bit integer so overflow should not be a problem. I think we need to find a way to reproduce, or get a such corrupted image to analyze what happened. Or, meanwhile, we can print additional info in "Create FS ..." for offset and size it has created, to see if the EFI was then zeroed by creation of other partitions.
Seeing this on falco release: https://luci-logdog.appspot.com/v/?s=chromeos/bb/chromeos/falco-release/3505/+/recipes/steps/Archive/0/stdout
Issue 850555 has been merged into this issue.
We are seeing this on the 67 branch also, has anyone had a chance to look at this recently?
