Public bug reported:
Binary package hint: linux-image
Bug #90271 and bug #187671 describe situations where Live CDs and
install CDs fail to work because a broken kernel module causes a hang
before user has a say. The error may be in an optional kernel module
(such as sound card driver or memory card reader) but the end user has
no way to prevent kernel from loading a possibly known broken module.
Vanilla kernels from kernel.org support flag disablemodules (e.g.
disablemodules=8139too,sdhci prevents linux kernel from loading
8139too.ko or sdhci.ko) but such flag does not seem to work with Ubuntu.
This is a feature request to enable such a flag. It is not needed for
normal use but in case of rare hardware exposing a bug in a kernel
module not having such a flag prevents one from booting Ubuntu. (I'd
prefer booting without network adapter or memory card reader to not
booting at all).
This issue also causes slowdowns such as bug #187671 which cannot
proceed until bug #90271 is fixed because testing possible fixes for the
bug is really hard until the other kernel module has been fixed. (This
is because both bugs affect the same laptop hardware and both kernel
modules cause a kernel hang.)
I'd consider disablemodules flag similar to acpi flag - it should not be
needed but still we need it.
