Description RHCOS Bug Bot 2021-09-23 06:01:51 UTC
Backport the fix for bug 2007085 to 4.7.

Comment 1 Benjamin Gilbert 2021-09-24 21:29:04 UTC
Fixed in 47.84.202109241831-0 on x86_64, and does not affect other arches.

Comment 2 RHCOS Bug Bot 2021-09-24 21:29:16 UTC
This bug has been reported fixed in a new RHCOS build.  Do not move this bug to MODIFIED until the fix has landed in a new bootimage.

Comment 3 RHCOS Bug Bot 2021-10-01 16:49:36 UTC
The fix for this bug has landed in a bootimage bump, as tracked in bug 1964753 (now in status MODIFIED).  Moving this bug to MODIFIED.

Comment 5 Michael Nguyen 2021-10-05 22:18:21 UTC
Verified on RHCOS 47.84.202109241831-0 which is the boot image for 4.7.0-0.nightly-2021-10-05-183054

Downloads live ISO and wrote to USB drive with
`dd bs=4M if=rhcos-47.84.202109241831-0-live.x86_64.iso of=/dev/sda oflag=sync status=progress`

Then booted USB drive and edited the kernel arguments to include
`udev.log_priority=debug`

`journalctl -u systemd-udevd.service --no-pager | grep rhcos` returned no symlinks pointing to /dev/sda2 or /dev/vda2
