Hello,

memtest86 was fine as well. No errors.

Seems that the hardware works like I except from IBM quality. 

Well lets see how that continues.

I probably write a kernel bug report about this later 2.6.17.1 and 
2.6.16.11 XFS crash... (dunno on which kernel it happened, since I had no 
kernel ooops)...

But it might not worth it. It may be better when I now use 2.6.17.1 only 
in order to be able to tell the exact kernel version and configuration 
under which corruption occured, should corruption occur again. But for I 
probably should update the SUSE 10.1 kernel to my 2.6.17.1 configuration 
as well.

BTW even blktool cannot query write cache:

root@deepdance:~ -> blktool /dev/hda wcache
it is not possible to query settings via command 'wcache'

Unless I may get this one to work:

root@deepdance:~ -> blktool /dev/hda i2o-wcache
BLKI2OGWSTRAT: Invalid argument

From manage:

       i2o-wcache
              Query or set an I2O block device's write cache.

Maybe with one of the next kernels I build, the current one doesnt support 
it:

root@deepdance:/boot -> grep "I2O" config-2.6.17.1-tp23-sws2-2.2.6
# CONFIG_SCSI_DPT_I2O is not set
# I2O device support
# CONFIG_I2O is not set

Regards,
