I am also affected..

[hangs]
The cause seems to be this modprobe command hanging:
$ ps ax | grep modprobe
4076 pts/4 S+ 0:00 modprobe --set-version=3.5.0-18-generic
--ignore-install --quiet --show-depends i915
I killed it, then tried to strace it from the command line to see what
it was doing:
# strace -f modprobe --set-version=3.5.0-18-generic --ignore-install --quiet
--show-depends i915
execve("/sbin/modprobe", ["modprobe", "--set-version=3.5.0-18-generic",
"--ignore-install", "--quiet", "--show-depends", "i915"], [/* 33 vars */]) = 0
....
This section of calls keeps on repeating forever..
open("/sys/module/i915/initstate", O_RDONLY) = 3
fstat(3, {st_mode=S_IFREG|0444, st_size=4096, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7ffa9b560000
read(3, "coming\n", 4096) = 7
close(3) = 0
munmap(0x7ffa9b560000, 4096) = 0
nanosleep({0, 100000000}, NULL) = 0

... etc.
Does anybody have any hint on how to fix this?
