Hello,

The current HPA handling implementation isn't robust enough and causes
regressions on several cases.  This patchset contains HPA handling
update.

* blacklist devices which puke on READ_NATIVE_MAX
* proper/better error handling - in most cases, HPA failure won't
  result in detection failure
* re-read IDENTIFY data after resizing
* more concise messages

Tested by setting up HPA area manually.
This is a bit big for 2.6.23-rc though :/
Agreed.  We can probably just get away with ATA_HORKAGE_BROKEN_HPA patch
for 2.6.23-rc but if we hit a device which is broken but isn't listed,
libata will fail to detect the device, which is a pretty serious regression.


PING.  Do you want me to separate out the blacklist patch for
#upstream-fixes and commit HPA error handling reimplementation only into
#upstream?

Works for me.
