[Bug 1876011] Re: Kernel Panic when dasd-fba device is selected for install
Checking the focal git tree this is included in the Ubuntu kernels:
Ubuntu-5.4.0-55.61
Ubuntu-5.4.0-56.62
Ubuntu-5.4.0-57.63
And Ubuntu-5.4.0-56 just migrated to updates:
linux-generic | 5.4.0.56.59 | focal-updates | s390x
hence I'm updating this (focal) to Fix Released.
** Also affects: linux (Ubuntu)
Importance: Undecided
Status: New
** Changed in: linux (Ubuntu)
Status: New => Fix Released
