Turns out "pcie_aspm=off" effectively disables AER because Linux doesn't
request AER control when it doesn't advertise ASPM support (see
ACPI_PCIE_REQ_SUPPORT). That explains why "pcie_aspm=off" would avoid
the error reporting.

The system hangs reported by lmbezeau and daniel-hartman are a separate

Blacklisting the nv_tco module is not a good long-term solution.
A recent upstream commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=6b01d30eef64456ad9e261d2173266a3244da8e1
looks like it could be a fix for this issue.

Thanks, Lisa, for testing this. I think the reason it didn't work was
because we made an error backporting it. I also noticed another problem
with the patch, so I attached a newer version here:

Anyone else affected by this Dell 1536/1546 issue, please test the
kernel patch at https://bugzilla.kernel.org/show_bug.cgi?id=31602#c21
and attach the results and dmesg log there.
I believe you will only see the issue if you have at least 3GB of memory
in your machine.

atimonin, I doubt that you're seeing the same problem. If you had the
same problem, no USB devices attached to the affected controller would
work at all. A complete dmesg log would have the details we need to be
sure.

Using "pci=nocrs" is a manual workaround, but not sufficient to resolve
this issue.

Thanks, Peter!
Here's what happens without "pci=use_crs":
ACPI: PCI Root Bridge [PCI0] (:00)
pci_root PNP0A08:00: host bridge window [mem 0xc000-0xfebf] (ignored)
pci :00:01.0: PCI bridge to [bus 01-01]
pci :00:01.0: bridge window [mem 0xbfe0-0xbfef]<= o
The normal method is to assume that all addresses to go the PCI bus
unless they're claimed by RAM or other builtin devices first. That's
certainly not true when we have more than one PCI host bridge, and
apparently it's not true even on some single-bridge machines like this
A355.
_CRS is the way
@Andy, if the "more specific fix" you refer to is a hotkey-setup change,
that is only a workaround and not a sufficient fix. The kernel should
never panic or hang, no matter what user-mode applications do. If you
pick up the kernel change from comment #32, the hotkey-setup change
should not be ne
As petski points out, this is very likely the same issue as
