wireless initramfs problem after upgrade to stretch from jessie (1 reply)

I have a dockstar booting from a USB card reader & 2 GB CF card.

Netconsole shows uboot version as follows.

U-Boot 2011.12 (Feb 12 2012 - 21:33:07)
Seagate FreeAgent DockStar
arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2009q3-67) 4.4.1
GNU ld (Sourcery G++ Lite 2009q3-67) 2.19.51.20090709

I was holding out for long time to upgrade from jesie to stretch. I finally gave in. Everything went smooth except following.

My wireless card stopped working. dmesg says

rt2800usb 1-1.4.3.3:1.0: firmware: agent aborted loading rt2870.bin (not found?)

It is supposed to be in firmware-misc-nonfree package according to Debian Wiki

This package is installed but I tried to reinstall it.Then I get the following hook message.

Preparing to unpack .../firmware-misc-nonfree_20161130-3_all.deb ...

I: The initramfs will attempt to resume from /dev/sda2

My fstab entry is as follows.

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/root       /               ext4    noatime,nodiratime,errors=remount-ro 0 1

So edited /etc/fstab.

I then tried uuid and fstype as (ext4 and also as auto)

I get

update-initramfs: deferring update (trigger activated)
Processing triggers for initramfs-tools (0.130) ...
update-initramfs: Generating /boot/initrd.img-3.2.0-4-kirkwood
Warning: couldn't identify filesystem type for fsck hook, ignoring.
Press Return to continue, 'q' followed by Return to quit.

How do I fix the hook and the wireless card issue?
