Bug 75733

 Im having trouble getting feedback, i have sent this email to quite a 
 few people with no responces. None. Hopefully someone out there can help 
 me out. I now have 2 extra network cards to send to people to help 
 testing. and tons of time to devote to this problem. Long time freebsd 
 promoter here, and my last step would be to run linux, and i would hate 
 to do that.
 
 Hi, i am running freebsd 5.3 with a Fore LE25, PHY=77105. I have been 
 using the IDT driver for over a year now. There is a bug in this driver 
 i belive, becasue every 2 days, both boxes i have running idt stop 
 passing traffic, and require a restart. When they hit the random 1-2 day 
 mark, they completely run out of mbufs and no traffic can be passed. (2 
 servers with 1 atm card, and 1 normal nic in each of them)
 
 Here are some things i have done or found out:
 I have experenced this problem from 5.2.1-5.3 (like i said about 1 year 
 now) I also have tryed putting alot of memory in the boxes, and setting 
 the mbufs to alot, kern.ipc.nmbclusters=131072 (after the new mbuf code 
 was commited) Setting kern.ipc.nmbclusters=0 casues no trafffic to be 
 passed on the atm card.
 
 The new version of idt.c casues my dmesg to be spammed. and all my cpu 
 eaten up with interupts. It looks like this
 idt0: <IDT IDT77201/211 NICStAR ATM Adapter> port 0x9400-0x94ff mem 
 0xe3004000-0xe3004fff irq 5 at device 6.0 on pci1
 idt0: [GIANT-LOCKED]
 idt0: ATM card is Fore LE25, PHY=77105
 idt0: 32K words of RAM
 idt0: MAC address 00:20:48:21:11:4e, HWrev=2
 idt0: i=  0, status=64320000
 idt0: i=  0, status=64320000
 idt0: i=  0, status=64320000
 idt0: i=  0, status=64320000
 idt0: i=  0, status=64320000
 <repeat>
 I tracked down where this was coming from, 
 http://fxr.watson.org/fxr/source/dev/idt/idt.c Line 3311. I recompiled 
 my system after removing lines 3310 and 3311. The driver no longer ate 
 all my cpu. But it still stoped passing traffic every 1-2 days.. I am 
 currently running both versions of the driver(one on each box), and they 
 break at about the same rate.
 
 Google, and man pages say i should use the harp, OR cranor driver. not 
 both.
 #ATM (cranor)
 #other

 #device          en

 #harp

 options         ATM_CORE                #core ATM protocol family
 options         ATM_IP                  #IP over ATM support
 options         ATM_UNI                 #UNI signalling manager
 options         ATM_SIGPVC              #SIGPVC signalling manager
 options         ATM_SPANS               #SPANS signalling manager
 
 Notes says that i should use one or the other, never both, and never a 
 mixture. Some things that have confused me, is my network card fails to 
 work unless device atm is uncommented. Also of the few places i found 
 online, people were using mixtures of each driver in there setup. I saw 
 alot of device atm, options atm_core, options atm_ip. Another thing to 
 note, is device idt does not work in the kernel, i have to load the 
 kernel module on boot.
 
 I can provide any information you need, just write me back. I am willing 
 to spend alot of time helping in any way i can to debug this. I can even 
 go as far as mailing one of the extra Fore LE25 atm network cards to 
 whoever needs it. I tryed the freebsd atm mailing list, and it seemed 
 quite dead. If there is someone else i should send this email too, or 
 something i could read, or extra information you need from me.
