Thanks for testing!

Ouch.

Hm, there didn't happen much in PCMCIA land between git7 and git10:

15ea76d407d560f985224b65fe59c9db01692a0d pccard: configure CLS on attach

which only seems relevant for CardBus. Nonetheless: could you try commenting
out the line "pci_set_cacheline_size(dev)" in
drivers/pcmcia/cardbus.c:cardbus_config_irq_and_cls() ?

However, my suspicion is that it is more related to PCI or serial work in
between... Does "lspci -vvv" change between -git7 and -git10?

Best,
