After upgrading 9.04 - 10.04, my automounts from LDAP no longer appear.
Instead, I get the following in dmesg at the rate of one per second:
[ 62.189700] automount[5011]: segfault at 0 ip 7f956cb1c022 sp
7fff3cd1a978 error 4 in libc-2.11.1.so[7f956ca99000+178000]

...
I guess something is trying to repeatedly respawn automount. Here's a
couple of pointers for anyone trying to debug (sensitive info turned to
