The connection seems to work very briefly during boot, so the user can get an IP over DHCP. After that point, the connection stops working. The adapter is integrated into a MSI K8N nVidia 4 Platinum motherboard. sky2 v1.5 addr 0xfe6fc000 irq 217 Yukon-EC (0xb6) rev 1 lspci: http://bugs.gentoo.org/attachment.cgi?id=92181&action=view This has all been reproduced on 2.6.18-rc2 with the "sky2: NAPI poll fix" patch on top (sky2 v1.5). sky2 v0.15 worked, and sk98lin works when he can get it to compile. This is being used on a half duplex 10mbps connection -- I'm only guessing, but I wonder if this might have something to do with the failure. Here is dmesg: http://bugs.gentoo.org/attachment.cgi?id=92182&action=view and /proc/interrupts http://bugs.gentoo.org/attachment.cgi?id=92183&action=view We also tried with the disable_msi parameter: dmesg: http://bugs.gentoo.org/attachment.cgi?id=92184&action=view interrupts: http://bugs.gentoo.org/attachment.cgi?id=92185&action=view When the connection drops, the interrupt counter is still increasing as normal. Any ideas? What extra info can we provide? Thanks, Daniel
