blacklist tileblit gets ignored

Did you update your initramfs after adding the blacklist to put the blacklist in there? Otherwise it's only checked after the HDD's are mounted which is well after it gets loaded.

UPDATE: I had fbcon and tileblit switched in the bug description. Both are blacklisted so it doesn't matter.

Robert Hooker: yes I did and it's not loaded if I do init=/bin/sh anyway

Here's a captured trace of who's trying to load fbcon. I got this by splicing modprobe on disk. Obviously I can't leave it that way or my system won't boot next time I do update-grub.

787 /sbin/modprobe -q fbcon
init-+-mountall---2*[fsck---fsck.ext3]
     |-plymouthd
     |-sh---find
     |-2*[udevadm]
     |-udevd-+-udevd---modprobe---pstree
     | |-69*[udevd]
     | |-2*[udevd---udisks-part-id]
     | |-udevd---blkid
     | `-udevd---modprobe---modprobe.distri
     `-upstart-udev-br

apport information

UPDATE: module killed by aliasing it to a non-extant module name

I'd like to append here some experiment that I made.

I wrote a file with all modules that I wanted to blacklist:

$ cat /etc/modprobe.d/blacklist-gadgets.conf
# Superfluous stuff
blacklist parport
blacklist lp
blacklist joydev
blacklist firewire_core
blacklist firewire_sbp2
# EOF

Then I ran 'sudo update-initramfs -u', rebooted and some modules were loaded again: parport and lp. I have no idea, since the port is already disabled at BIOS and the other three modules weren't loaded.

$ dmesg | grep lp:
[ 22.345235] lp: driver loaded but no devices found
