Description of problem: I have several Sun X2100 that have this ethernet controller: 00:0a.0 Ethernet controller: nVidia Corporation CK804 Ethernet Controller (rev a3) I had 2 machines drop off the network over the weekend. They had the following errors: nv_stop_tx: TransmitterStatus remained busy<7>eth1: tx_timeout: dead entries! NETDEV WATCHDOG: eth1: transmit timed out eth1: Got tx_timeout. irq: 00000000 eth1: Ring at 374a7000: next 63 nic 0 eth1: Dumping tx registers <dump> eth1: Dumping tx ring <dump> These machines were setup with 802.1Q turned on and a native vlan and 3 other vlans trunked to this interface. The interface was quite busy. I've seen several emails and postings that lead me to this kernel bug. http://bugzilla.kernel.org/show_bug.cgi?id=4552 Version-Release number of selected component (if applicable): Linux uni20wr.unity.ncsu.edu 2.6.9-42.0.3.EL #1 Mon Sep 25 17:14:19 EDT 2006 i686 athlon i386 GNU/Linux

Jack, please try the kernels here: http://people.redhat.com/jbaron/rhel4/RPMS.kernel/ Do you still experience the problem when using these kernels?
Closed due to lack of response...please reopen with the requested test results if the problem remains. Thanks!
