udevd writes syslog messages on the screen

[Florent]

Binary package hint: cryptsetup

Usplash is not active. The argument "quiet" is passed to boot.
There's lots of messages printed by udevd on the screen during boot: see file attached.

It happens when cryptsetup is installed.
More precisely, the problem occurs when /lib/cryptsetup/askpass is called.

user@jaunty$ cat /proc/cmdline
root=UUID=9ceb4b9e-7677-4031-a6da-1996e3542ca2 ro quiet vga=789

But these "udevd" messages are not printed on screen if :
 - the "askpass" invocation is removed from "scripts/local-top/cryptroot"
 - or if the package cryptsetup is not installed

Askpass is faulty. It changes the "kernel.printk" parameter, but it does not revert to the previous value.

user@jaunty$ cat /proc/sys/kernel/printk
4 4 1 7
user@jaunty$ sudo /lib/cryptsetup/askpass "Test "
Test password
user@jaunty$ cat /proc/sys/kernel/printk
7 4 1 7

and the workaround is to save the kernel.printk parameter before calling "askpass" and restore it after.
