With 2 wheek work, i have tracked down the problem, to exactly one thing. This only happens, when i use NBD with BS=4096 option on the MTU 1500 network. I know exactly the concentrator makes the "bad thing", (NETDEV WATCHDOG: eth0: transmit timed out e1000: eth0: e1000_watchdog_task: NIC Link is Up 1000 Mbps Full Duplex) but the nodes are vulnerable, and rebootabe over the network. I am not sure, wich have the bug, the NBD-server, or kernel, but if the nbd-server have the bug, the kernel cannot handle correctly, and this is a security issue. The nodes are equal. (2.6.16-rc2-git5) The concentrator is: [EMAIL PROTECTED] /]# uname -a Linux dy-xeon-1 2.6.15-rc5-NBDFIX #2 SMP Thu Dec 29 19:04:16 CET 2005 i686 i686 i386 GNU/Linux (The NBDFIX is mean Herbert Xu's NBD-patch in client) Thanks, Janos - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
