[SOLVED] Cannot Boot After Low Battery Shutdown (ACPI Error?)

I ran my laptop a bit low (down to 4% battery) and then shut it down with 'sudo halt'. The shutdown process appeared to complete without a hitch i.e. it didn't seem like it ran out of battery while shutting down.

But upon booting up again, it gets stuck

ACPI: SSDT (null) 00085 (v02 PmRef Cpu1Cst 000030000 INTL 20050624)
ACPI: Interpreter Enabled
ACPI: (supports S0 S1 S3 S4 S5)
ACPI: Using IOACPI for interrupt routing
ACPI: EC: GPE = 0x1d, I/O: command/status = 0x66, data = 0x62
ACPI: No dock devices found.
HEST: Table not found.
PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug
ACPI Error: [CAPB] Namespace lookup failure, AE_ALREADY_EXISTS (20110112/dsfield-143)
ACPI Error: Method parse/execution failed [\_SB_.PCI0._OSC] (Node f50305b8), AE_ALREADY_EXISTS (20110112/psparse-536)
ACPI: Marking method _OSC as Serialized because of AE_ALREADY_EXISTS error
ACPI: PCI Root Bridge [PCI0] (domain 0000) [bus 00-3f])

and then there are a bunch of lines like

pci_root PNP0A08:00: host bridge window [mem 0x000a0000-0x00bffff]

and it's still sitting there doing nothing. What shall I do?

Edit:
Okay, so the fallback image works fine, but I still don't know what's wrong with the normal one so I don't know what to fix!

Re: [SOLVED] Cannot Boot After Low Battery Shutdown (ACPI Error?)

Does the newest kernel still not work at a full battery charge?
Found and interesting link here, might want to try this:
"UPDATE:

my machine is running fine for 2 weeks now with pcie_aspm=off boot option.

I figured out that the problem must be related to pci express devices since they were not detected during pci probing on a fail- boot. (As you can see in the log above and with help of lspci to identify the missing devices)

for further reference see:
http://www.kernel.org/doc/Documentation … meters.txt

I hope that will help also others who have the same issue. This might also be helpful:

Re: [SOLVED] Cannot Boot After Low Battery Shutdown (ACPI Error?)

Sorry for the lame resolution, but it seemed to fix itself. I restarted and everything appears to work fine. I checked dmesg, and those same errors show up even when it boots properly, so I'm guessing that it was some weird one-time error.
