Svante bisected it to v2.6.34-rc1~218^2~27 (x86/pci: Use resource_size_t in update_res, 2010-02-10) --- thanks. Which is pretty weird, since I think phys_addr_t on an amd64 machine (and hence resource_size_t) would be 64 bits, making that commit a no-op. Svante, more questions (sorry): - could you try booting b74fd238a9cf and b74fd238a9cf^ again (to make sure we haven't hit a heisenbug) and send the corresponding full dmesg and .config files?
