 Jeff, I shall send all the sata patches which I have at you one 
 single time
 and I shall then drop the lot.  So please don't flub them.

 I'll then do a rc1-mm2 without them.
 hm, this is looking like a lot of work for not much gain.  Rafael, 
 are
 you able to do a quick chop and tell us whether these:

 pci-move-pci_vdevice-from-libata-to-core.patch
 pata_cs5530-suspend-resume-support-tweak.patch
 ata-fix-platform_device_register_simple-error-check.patch
 initializer-entry-defined-twice-in-pata_rz1000.patch
 pata_via-suspend-resume-support-fix.patch
 sata_nv-add-suspend-resume-support.patch
 libata-simulate-report-luns-for-atapi-devices.patch
 user-of-the-jiffies-rounding-patch-ata-subsystem.patch
 libata-fix-oops-with-sparsemem.patch
 sata_nv-fix-kfree-ordering-in-remove.patch
 libata-dont-initialize-sg-in-ata_exec_internal-if-dma_none-take-2.patch
 pci-quirks-fix-the-festering-mess-that-claims-to-handle-ide-quirks-ide-fix.patch

 are innocent?
 
 Yes, they are.

We all really appreciate your patience :)  This is good feedback.

To narrow down some more, does applying 2.6.20-rc1 + the attached patch 
work?  (ignoring -mm tree altogether)
   
   Yes, it does.
  
  I've applied the patches from -rc1-mm1 up to and including
  
  problem-phy-probe-not-working-properly-for-ibm_emac-ppc4xx.patch
  
  on top of 2.6.20-rc1 and they don't seem to break anything.  Will try some
  more.
 
 The patch that breaks things is somewhere between
 
 dont-export-device-ids-to-userspace.patch
 
 and
 
 funsoft-is-bust-on-sparc.patch
 
 inclusive.
 
 Now I'll need to resync my disk arrays so if anyone has any suggestions
 what to try next, I'll be grateful. ;-)

Okay, I have identified the patch that causes the problem to appear, which is

fix-sense-key-medium-error-processing-and-retry.patch

With this patch reverted -rc1-mm1 is happily running on my test box.

Greetings,
Rafael

That was rather unexpected.   Thanks.

I can confirm that 2.6.20-rc1-mm1 with this patch reverted mounts my
raid6 partition without problems. This is x86_64 with SMP.

Kind regards,
