I have an amd64 system with an old 3.3.x kernel. Recently (I think after
|
2 |
last udev update to 217) the boot process became very slow due to "udev
|
3 |
waiting for uevents to populate /dev". After a minute or so udev prints
|
4 |
something about a lazy device (a TV tuner) then the boot continues.
|

Yesterday I tried to update the kernel to 4.0.2. On first boot no udev
|
7 |
delay. Then I had to reboot into 3.3.x and from then on 4.0.2 does not
|
8 |
boot any more, it hangs endlessly in the "udev waiting" state. 3.3.x
|
9 |
still behaves as before (slow but works).
|

I removed the TV tuner hardware but no change.
|
12 |
|
13 |
Since problems in 4.x started after I booted into 3.x, could it be that
|
14 |
udev saved some state that makes the 4.x boot process fail?
|
15 |
Any hints to debug this issue?
