Thanks very much!
"ACPI: EC: Look up EC in DSDT" appears in the working log, but not
in the broken one. But I think we *do* find the EC in both cases,
because we see "ACPI: EC: non-query interrupt received" even before
acpi_ec_add() (which prints the "ACPI: EC: GPE = 0x1c, ...". Maybe
the logs were collected with different log levels?
I think Alexey is on the right track with the PCI resource allocation
failure. On your working kernel, can you collect this:
lspci -vv > lspci
cat /proc/ioports > ioports
cat /proc/iomem > iomem
grep . /sys/devices/pnp*/*/resources > pnp
tar -jcf resources.tar.bz2 lspci ioports iomem pnp
