[Vasiliy Tolstov]

Hi all and sorry for may be spamming mailing list.

I have acer aspire v5-17 with broadcom card reader and ethernet card.
I'm affecting on this ubuntu bugs. But bug is present in vanilla linux
current git and stable lts.

Can somebody helps me and say - where i can post message and discuss
this problem. As i see ubuntu team can't solve this problem (bug
present is about 1 year and nothing changed).
One ubuntu user wia bisecting find broken commit -
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=6cac12dfab9c57a4f76821412224b226a9b08dff

Relevant ubuntu bugs:

[+cc linux-pci because I think this is related to PCI ASPM]

I'm afraid nobody wants to touch ASPM because it's such a mess, but I
hope somebody will step up and investigate this.

So apparently this machine got broken when we changed the behavior for 
the ACPI ASPM-not-supported bit from forcing ASPM off for everything to 
leaving ASPM in whatever state the BIOS left it in. And apparently for 
some reason the device (devices?) doesn't work with ASPM enabled in 
Linux but does in Windows. It's possible that some other workaround is 
being applied by the Windows driver that allows it to work there.

I'm not too sure what the next step to debug that would be, unless maybe 
someone has a contact at Broadcom. We could conceivably add a quirk to 
force ASPM off for this device regardless of what the BIOS says, though.
