I have many errors in dmesg like the ones below. If I count just the lines that match the first one, there are over 1500. If I include the suppressed lines it is over 100k. At first I got three of these doing something and then didn't see it for a while. I suspect the 100k came from a download of an 8gb file from the internet that was being written to the remote machine via iSCSI. The download took about an hour and fifteen minutes. I would ignore just three of these, but 100k of them suggests a real problem to me. sky2 0000:02:00.0: error interrupt status=0x8 printk: 77 messages suppressed. I am using a MTU of 9000. Between the two computers is a D-Link *DGS-2208 *switch that supports jumbo frames. The remote card uses the forcedeth driver. This from the kernel package changelog seems like it might apply. * Mon Jul 09 2007 Chuck Ebbert - sky2: restore workarounds for lost interrupts Local dmesg: sky2 0000:02:00.0: v1.18 addr 0xfe8fc000 irq 17 Yukon-EC Ultra (0xb4) rev 2 Local lspci: 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12) Local iSCSI Initiator software: iscsi-initiator-utils-6.2.0.865-0.2.fc8.x86_64 Remote dmesg: forcedeth.c: Reverse Engineered nForce ethernet driver.
