mdadm update throws up grep error

[Frex]

This is the interesting bit (full pastebin here)

$this->bbcode_second_pass_code('', '(6/6) upgrading mdadm [######################] 100%
grep: /etc/mkinitcpio.conf: No such file or directory
')

Also after updating the kernel I got a bunch of:

$this->bbcode_second_pass_code('', 'localhost modprobe: FATAL: Could not load /lib/modules/2.6.37/modules.dep: No such file or directory')

The file is gone like the whole /lib/modules/2.6.37/ , but why would it try modprobe-ing in the first place?
