Re: [Libreboot] new T400 beta ROMs for testing

[Persmule]

   Hi Leah,
   I manage to do bisect myself.
   I have noticed that the coreboot revision used by t400 has changed
   around Jul 17:

     $ git diff 23048a4 HEAD
     resources/libreboot/config/grub/t400_8mb/cbrevision
     diff --git a/resources/libreboot/config/grub/t400_8mb/cbrevision
     b/resources/libreboot/config/grub/t400_8mb/cbrevision
     index 1ab8299..d4e47be 100644
     --- a/resources/libreboot/config/grub/t400_8mb/cbrevision
     +++ b/resources/libreboot/config/grub/t400_8mb/cbrevision
     @@ -1 +1 @@
     -2a3434757ef425dbdfedf1fc69e1a033a6e7310d
     +d83b0e9ac4174cca92ac2c3b83a7e8491a9a1ff4

   Is it possible to do bisect like below?

     start bisect on coreboot's repository between the two revision, then
     write the current coreboot revision number given by $git show -s to
     resources/libreboot/config/grub/t400_?mb/cbrevision, then build
     libreboot as usual and flash and test, then mark the current
     revision on coreboot's repository and recurse.

     I made some changes to ich9gen, relating to the descriptor, some
     time
     ago. We found for instance that the "component density" section was
     wrong, so we fixed that. There were some other minor changes. Users
     have reported working wifi with those newer descriptors in earlier
     snapshots. The 96 snapshot uses a new revision of coreboot and as
     far
     as I know, this is all that has changed, aside from some minor
     patches
     changed which also shouldn't (in my opinion) affect wifi. We think
     upstream (coreboot project) might have broken it, so someone will
     have
     to bisect coreboot to see if there is a regression, and if so on
     what
     commit.
