I only addressed the pcmcia probe failure that you reported for the
final pxa patch, which
previously caused a NULL pointer reference here:

[    1.405319] PC is at pcmcia_init_one+0xf8/0x27c
[    1.405476] LR is at devres_add+0x40/0x6c
[    1.405611] pc : [<c04bdea0>]    lr : [<c044d808>]    psr: a0000113
[    1.405846] sp : c48a5d00  ip : c15f4220  fp : 60000113
[    1.406026] r10: 00000000  r9 : c48b000e  r8 : c48b0000
[    1.406195] r7 : feeb0000  r6 : feeb000e  r5 : c15ec090  r4 : c15ec020
[    1.406395] r3 : 00000002  r2 : 00000000  r1 : c15f4200  r0 : feeb000e

This now seems to work:

[    1.435846] pcmcia_socket pcmcia_socket1: pccard: PCMCIA card
inserted into slot 1
[    1.456350] pcmcia_socket pcmcia_socket0: pccard: PCMCIA card
inserted into slot 0
[    1.457489] pcmcia 0.0: pcmcia: registering new device pcmcia0.0 (IRQ: 217)
[    1.460275] pata_pcmcia: probe of 0.0 failed with error -12

So it sounds like there are additional bugs that I have to look at. I
probably won't
be able to do that in time for the merge window. The logs contain a number of
warnings, but I have no idea which ones of those are preexisting issue. I had
a look at

[    0.689982] pxa-dma pxa-dma.0: error -ENXIO: IRQ index 1 not found

and concluded that it must have done this for a long time. In my own qemu
instance, I see a crash from iWMMXt, but that works fine on your machine.
OTOH, your failed instances all look like they either time out or
failed to find a
rootfs. I tried passing an MMC device as root, and that works here.
