Why is MSI disabled on this motherboard? Is it because of the AMD chipset or did you explicitly turn it off.? I haven't disabled MSI. BTW, I don't even know what it is. Several timeout fixes (related to flow control) went into later versions of 2.6.21-rc4? and stable kernels 2.6.20.6. Please try and reproduce with more recent kernel. |
Most recent kernel where this bug did *NOT* occur: N/A Distribution: Gentoo amd64 2006.1 Hardware Environment: Asus A8R32-MVP Deluxe, Athlon64 3800+ x2, 2 x 512MB RAM Software Environment: Problem Description: I was trying the updated sky2 driver in 2.6.21-rc1 on my server running a Gigabyte GA-965P-DS4 (FW: F8) motherboard with Marvell 8053 chip, Intel Core 2 Duo CPU. After approx. 48-72 hours, I lost almost all speed (going down to approx. 15 kB/s) in uplink direction and sometimes lost connection completely for a shorter while. I'm not sure what happened with my speed in downlink direction. I then went back to Marvell own driver patched into a 2.6.20 kernel on the server. Meanwhile I started to try to reproduce it on my lab PC running a Asus A8R32-MVP Deluxe motherboard (FW: 0602) which have two Gb LAN; one Marvell 8001 on the PCI bus and one 8053 on the PCIe bus, Athlon64 3800+ x2 CPU. I installed 2.6.21-rc1 on this machine too, and started to use the 8053 with the sky2 driver. Made a lot of FTP transfers in both direction, but mostly uploads to stress the uplink direction. And after approx. 34 hours, I see the same symptom on this machine too. A reboot recovers the bad speed. Some system info (please tell me if you want more or other information): dmesg: ====== ...

Do a lot of transfers and wait 48 hours or more. Hopefully something bad happens.
