If you only see this with an external S-ATA box and a long cable, we

Can you summarize/repost the log of the panic with the linux-ide

Hi Ric,
sure, here's summary of the problem:
After upgrading my box to 2.6.32.x, it started crashing while copying larger amounts of data (backtraces follow). I did a lot of testing, and it always happens, when the target disk is connected using external eSATA box and using long (~1M) eSATA cable. In this case, it's enough to start 2 parallel copying processes, and crash follows within minutes (tested on two different machines, using two differrent boxes). I first thought it doesn't happen with shorter eSATA cable, but leaving copying running in cycle for hours invoked crash as well - so it just takes much longer. It never happens while using standard SATA cable with directly connected disk. So now my concerns are:
- if the box is screwing data, then kernel maybe could behave in better way then just crashing with lots of backtraces.
- it's strange that with older kernels (<= 2.6.31.x) it *SEEMED* to work. I plan to repeat tests with older kernels, and with checking MD5 of written data to see if it was writing data correctly, or just not noticing something is wrong.
- the whole thing leads me to another question - what is the current state of block device integrity support? I haven't found much information about it, do common SATA drives support it? Can filesystems like ext4 use it?
Anyways, if there is anything else I could do/test, please let me know. Since I can reproduce the problem on testing box, I'm free to test new kernels, git snapshots, bisect, whatever :)
cheers

Hi Nik,
The interesting thing (or lack of interesting thing) is that I do not see any IO
errors. I would expect to see something if your e-SATA enclosure and the s-ata
cable length are prducing bad data.
Are there any IO errors in the log before the stream of file system issues?
Thanks!
