First of all thanks a lot for the great job!
The issue is identical to http://zen-kernel.org/issues/15 on 2.6.33-zen1.
I get many random "SQUASHFS error: read_indexes: reading block/Unable to read directory block/Unable to read inode"
in dmesg by using squashfs+aufs.
The switch to the vanilla kernel26 2.6.32.10 on Arch Linux without changing anything on compressed image solves the problem.
In kernel release notes appears squashfs and aufs however, so do I miss something in my kernel config ?

Steps to reproduce:: used this guide http://wiki.archlinux.org/[…]/Maximizing_performance#Compressing_.2Fusr

I can confirm this.
I believe it still enherit problem from http://zen-kernel.org/issues/15.
It could be caused by introduction of lzma into squashfs.
Squashfs alone (without aufs) will have errors reading compressed file.
System sometime will hang while trying to mount with option -t squashfs -o loop.
Now using vanilla 2.6.33.1 with unionfs without problem.

I also have this problem.
I use aufs and squashfs to mount /usr on my gentoo system.Sometimes I got this error "kernel: SQUASHFS error: Unable to read inode".After rebooting one time even several times,everything went well again.
This morning I decided to recompile zen-kernel to see if there would be any improvement.Unfortunately,after zen-kernel was recompiled,the problem became worse.EVERYTIME I boot/reboot my system,I get the error "kernel: SQUASHFS error: Unable to read inode" and many apps can't be executed.
For the moment I have to try to compile vanilla-kernel to rescue my system.

"Me too".
But using plain squashfs (without aufs) seems to work ok.
I haven't tried with a vanilla kernel.

Is this still a bug in 2.6.35 or 2.6.36?
