Zaurus model: 5500
kernel version: 2.4.18-rmk7-pxa3-embedix
opie
last upgrade date: fresh install

After installing 2.5.3 I was merrily oz-ing along when I decided to shutdown. I did so and reboot proceeded normally through the opie startup...then no opie, just a blank screen.

I docked it and luckily usb networking was up, so I ssh'd over and started opie from a console so I could read the messages. They appeared normal, but no opie.

To make a long story short, I stumbled into the /var directory and it was totally empty.
Plus, tmpfs is mounted over var multiple times.

root@collie:/# df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/mtdblock4 14464 13624 840 94% /
/dev/mtdblock6 31729 18 30073 0% /media/ram
tmpfs 15080 0 15080 0% /var
/dev/mmcda1 241145 97299 131395 43% /media/card
tmpfs 15080 0 15080 0% /var
tmpfs 15080 0 15080 0% /var
tmpfs 15080 0 15080 0% /var
tmpfs 15080 0 15080 0% /var

Of course the z is unusable. This has happened with multiple installs and two different 5500s.

Note: I just discovered that if I reboot and unmount /var the contents are recovered. So empty filesystems are being mounted over /var??

Note2: This remounting of /var is happening continually. I "fixed" things for now by tarring up /var and recreating it in /media/ram. I then commented out the tmpfs->/var mountpoint in fstab and made /var a symlink to /media/ram/var.

Note3: As expected, the "fix" didn't work smile.gif

Whoa!

Total install killer for a 5500 and _no-one_ responds? I'd discount it as holiday-weekend blahs, but developers are responding elsewhere.

Where are the Oz-Team developers? Lardman, Mickey, whomever?

When booting a fresh install of OZ 2.5.3 my /var dir is hosed within _minutes_.

Is it that the 5500 is of no concern?

This happens on two different 5500s.

I can't reproduce that here, sorry.

Are you sure that you didn't install any additional software before this happens?
Or did you apply some tweak to your OZ?

/var works as expected on my device.
