Hi, I have searched the archives, but I can't seem to find anything exactly like what my user is experiencing.
The system is running kernel 2.6.18-194.8.1.el5. The problem has also occurred with kernel 2.6.29 from kernel.org. The system contains the following add-on card: http://www.intel.com/products/server/adapters/pro1000mt-dualport/pro1000mt-dualport-overview.htm # lspci | grep 82546 02:01.0 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03) 02:01.1 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03) Seemingly randomly, the following error message appears in the kernel log, then the interface starts dropping all traffic (no errors, just drops): irq 209: nobody cared (try booting with the "irqpoll" option) Call Trace: <IRQ> [<ffffffff800bb712>] __report_bad_irq+0x30/0x7d [<ffffffff800bb945>] note_interrupt+0x1e6/0x227 [<ffffffff800bae41>] __do_IRQ+0xbd/0x103 [<ffffffff8006ca11>] do_IRQ+0xe7/0xf5 [<ffffffff8006b346>] default_idle+0x0/0x50 [<ffffffff8005d615>] ret_from_intr+0x0/0xa <EOI> [<ffffffff8006b36f>] default_idle+0x29/0x50 [<ffffffff80049150>] cpu_idle+0x95/0xb8 [<ffffffff8007796f>] start_secondary+0x498/0x4a7 handlers: [<ffffffff88211d7b>] (e1000_intr+0x0/0x12c [e1000]) Disabling IRQ #209 At this point, the user must power off / pull card / power on / power off / put card back in. This is only a temporary fix, sometimes it works again for only an hour, sometimes for weeks/months. This happens with both the stock Redhat kernel driver: Intel(R) PRO/1000 Network Driver - version 7.3.21-k4.1-NAPI And the driver from Sourceforge: # ethtool -i eth3 driver: e1000 version: 8.0.19-NAPI firmware-version: N/A bus-info: 0000:02:01.1 Since the problem is hard to reproduce, would it be helpful to have the user collect a vmcore via kdump when it happens?
