2.6.19 (current from git) on SPARC64: Can't mount /

[Horst H. von Brand]

I've been running kernel du jour straight from git on my SPARC Ultra 1 for
some time now on Aurora Corona (Fedora relative, development branch). For a
few days now 2.6.19 panics on boot, it can't mount /. 2.6.19 worked fine,
as does 2.6.19.1 (Aurora changed gcc, mkinitrd, ... in between, so I had to
rebuild a kernel to check if the problem lay elsewhere). Unpacking the
initrds for 2.6.19 and 2.6.19.1 shows the same (nash script) /init and the
same modules in both (ext3 + jbd, scsi_mod, sd_mod, esp, others).

I'm stumped. Any clue?

Is this issue still present in the latest -git?

not 100% sure here.  Check the size of the initrd.  kinda sounds like an issue 
that hit rawhide last week that needed a new mkinitrd.  if its smaller grab 
the srpm from the Fedora Development tree for mkinitrd and rebuild it.  then 
recreate your initrd and see if that works.

Sorry, got sidetracked by other stuff.

Still no boot with 2.9.20-rc1 and -rc2, and none of the kernels I tried in
between.

initrd is sane (the only differences between the one built for working
2.6.19.1 and broken 2.6.20-rc2 are among the modules themselves). What I
did was:

  cd /tmp
  mkdir ird-$version
  cd ird-$version
  zcat /boot/initrd-$version.img | cpio -i

and then "diff -Nur ird-$1 ird-$2". Now to teach diff(1) to compare devices
reasonably...

Tried latest from Fedora rawhide (mkinitrd-6.0.6-1), no boot. initrd is
huge, so I went back to mkinitrd-5.1.19-1.
