I have a Sandy (soon Ivy) Bridge based HTPC/NAS.

The motherboard originally was an ASUS P8H67M-PRO B3. It worked
quite fine. I had a problem with a BIOS update and while it was being
fixed I bought a Gigabyte H77M-D3H.

This board has a nasty problem with its ACPI tables and cannot suspend.

Since I'll be upgrading to an Ivy Bridge i7 pretty soon I wanted to keep
the Ivy chipset but I need it to suspend/resume reliably.

So, do you know of any actual motherboard with an H77 or Z77 (preferably
the latter), micro ATX, with one PCI slot which works well in Linux?

Or more in general, which current consumer motherboards work well in Linux?

The issue I have is also present in Asus and Intel motherboards, not sure
about ASRock or MSI: https://bugzilla.kernel.org/show_bug.cgi?id=43229
