![]() I've been plagued by these problems on two rack servers in the past (one slightly older, PCI based - the other a bit newer, with two onboard cards based on PCIe) and an Intel e1000e/ PCIe desktop card. One guide (for a slightly older chipset revision) I can find quickly about this issue would be 82573(V/L/E) TX Unit Hang Messages, you'd need to check up on the details for your revision yourself - be aware that this hot patching via ethtool is risky business and might destroy your card for good (backups, backups, backups, they might not help under all circumstances, but it's better to have them than not). On several e1000/ e1000e chipsets you can mitigate this by (permanently) binary patching the card's EEPROM using ethtool, which effectively disables the problematic powersaving features in hardware. The result of this are dropped packets and silent data corruption, these cards are effectively defective (and while less prominent, it also affects windows or other operating systems). This is a firmware (EEPROM) issue that has plagued PCI and early PCIe e1000/ e1000e chipsets for years, it's effectively a problem with powersaving features interfering with normal operations. I used LSPCI and the cards areĠ0:19.0 Ethernet controller: Intel Corporation 82567LM-3 Gigabit Network Connection (rev 02)Ġ2:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network ConnectionĮ1000e 0000:00:19.0 eth0: Detected Hardware Unit Hang: It looks like the ethernet card is hanging, may be a driver issue.
