SATA exceptions triggered by XFS (since 2.6.18)

[Paolo Ornati <ornati@fastwebnet.it>]

Sorry for starting a new thread, but I've deleted the messages from my
mail-box, and I'm sot sure it's the same problem as here:

Today I've decided to try XFS... and just doing anything on it
(extracting a tarball, for example) make my SATA HD go crazy ;)

I don't remember to have seen this using Ext3.

I've so far tested these kernels:
2.6.20-rc5	BAD
2.6.20-rc4	BAD
2.6.19		BAD
2.6.18		BAD
2.6.17		Good !

I'll start a git-bisection...
