At present the known open skge, sky2 issues are: 1) Skge doesn't work with dual port fiber 2) Sky2 (and vendor sk98lin) don't work on some MSI motherboards due to PCI issues 3) Skge and sky2 trigger problems with motherboards that don't do >4GB DMA correctly. Not a driver but a PCI quirk problem. 4) Sky2 does polling for lost irq even when interface not up 5) Sky2 polling rate for lost irq maybe greater than TCP timeout so connection may be lost even after link recovers 6) Sky2 Yukon extreme support is still experimental and fragile, but this hardware isn't in the wild yet 7) Sky2 Yukon EC-U not powering up PHY correctly on some revisions 8) Sky2 suspend to ram not working right on some chips Hardware nuisances that are being masked: a) hardware can't DMA to unaligned address b) polling for lost irq is a hack, but until the root cause is found it will have to stay.
