noautoconfig disables a check while booting in userland at the grml
system.  What I'm doing there is:

* check for existence of /dev/fd0; if it exits:
* run 'if dd if=/dev/fd0 of=/dev/null bs=512 count=1', if successful:
* run blkid to identify devices with a specific label (GRMLCFG)

noautoconfig disables this check at all.

Booting grml on a system with a fd-connector but no fd present at
all provides the following syslog entry:

  end_request: I/O error, dev fd0, sector 0

which I could also find in #373594.

Marc, does the same behaviour (hanging for ~2 min) occur on harddisk
installation or is it just at d-i?

IMHO this looks like an userland application is trying to access
/dev/fd0 several times (as the 'end_request: I/O error...' is
present several times). This usually happens when scanning for
disks/partitions/... Might this be the case, Frans?
