Hi,

when I call "s2ram -f -p" from  vt1 on my HP TC1100, the system suspends 
fine, and
when resuming,  it even comes back showing the command prompt, but only 
after
an avalanche of error messages like:

[ 1598.962543] EXT3-fs error (device sda3): ext3_find_entry:
reading directory #1025639 offset 0

After that, any access to the harddisk (e.g. calling commands like ls) 
results
in similar EXT3-fs error messages.

On the other hand, suspend to ram works fine when I install on a USB 
stick, so the
problem seems to be related to the harddisk subsystem. Furthermore,  the 
hardware
itself seems to be fine, as s2ram works with Windows XP.

I tested with a vanilla 2.6.30 kernel.

Please let me know if any further debugging information is required.

Thanks for any help,

Christof
