I now am fairly certain that the problem (network stalls on multiprocessor systems) is not BP6 or NE2K-PCI specific. I found several postings which relate to similar problems on dissimilar hardware. Another interesting one is: Re: PROBLEM : Networking stops working with kernel 2.4.0-test11 (http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg18722.html) "...I have an almos identical system as you, 2x200MMX motherboard (Gigabyte 586DX) also Voodoo3 (2000 pci) the same nic Realtek 8029AS, also a bt848 tv card, also SCSI (Aic-7880 onboard, but not used). I have reported it some time ago, and now all I get with 2.4.0-test11-pre4 and I think a additional patch is NETDEV WATCHDOG: eth0: transmit timed out, and something in the console about lost irq? I can't reproduce it with a uniprocesor kernel, and I have a 3c503 card wich uses the 8390 module, so I suppose that the problem it's not in the 8390, and it seems to be smp related...." ne2k-pci freezes with APIC error on 2.4.0-testX SMP (http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg14468.html) "... When doing massive NFS transfers (2.4 machine as the client) on my SMP box (Abit BP6 2x celeronA 533mhz (non-overclocked) 64Mb ram, latest apt-get-ed debian woody) my ne2k-pci card (Realtek Semiconductor Co., Ltd. RTL-8029(AS) (rev 0)) suddenly stops working. test5 spits that in syslog:..." More to be found when searching the archives. This problem has been around for a long, long time (probably since the current level of apic-support was added, somewhere around 2.3.1x?). It has been reported by several people, several times. I feel like rigging every apic-related piece of code with a zillion bells and printk's but that would surely only create more mayhem as this whole thing seems to be timing-related... Anyone got any idea's on how to tackle this? Anyone who is 'intimate with' the apic-related code? It'll take me some time to dive into that part, so if there is anyone who already has taken the plunge, do tell...
