I am experiencing breaking of connections with drbd. The nodes have two Gigabit nics and are linked by a crossover Gigabit cable. The first node (master) boots and awaits for the second (slave) to connect. When slave starts the drbd service I get this messages: Setting up 'drbd0' .. disk ok .. net .. OK drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 drbd0: magic?? m: 0 c: 0 l: 0 drbd0: unacked_cnt!=0 And, sometimes, the system hangs. On the master node the following messages are displayed: drbd0: sock_sendmsg returned -32 drbd0: syncer send failed!! drbd0: Syncer send failed. drbd0: sock_sendmsg returned -32 drbd0: syncer send failed!! drbd0: Syncer send failed. drbd0: sock_sendmsg returned -32 drbd0: syncer send failed!! drbd0: Syncer send failed. drbd0: sock_sendmsg returned -32 drbd0: syncer send failed!! drbd0: Syncer aborted. drbd0: sock_sendmsg returned -32 drbd0: syncer send failed!! drbd0: Syncer send failed. drbd0: sock_sendmsg returned -32 drbd0: syncer send failed!! drbd0: Syncer send failed. And sometimes and protection fault is raised, but the system doesn't hangs. Both master and slave nodes uses the TEG-PICTX2 (NWay Cooper Gigabit Ethernet Adapter) nic. The kernel modules that I've tryed were the ns83820 (suggested by kudzu) and the dpm (supplyed by the vendor). I downloaded the more recent driver version from the vendor's site (www.trendnet.com), but, for my great surprise, the module doens't compile due to many compilation erros. I notifyed the vendor's support and asked for the new release, but they send me the same old version that I already have. Bellow are the /var/log/messages from the both nodes: (on master) ..

The kernel is 2.4.22 and the distro is RH9. Any help will be very appretiated. If this informations were not enough, please ask me for more datails. Thanks in advance.
