Message-ID: <4B64A902.90800@web.de> Date: Sat, 30 Jan 2010 22:47:46 +0100 From: Lee <lee-in-berlin@....de> To: netdev@...r.kernel.org Subject: Several OOPSes in net/sched/sch_generic.c, kernel/softirq.c (and other places) Hello there, I have witnessed several kernel oopses in a vanilla 2.6.32 kernel of different patch levels. The only effect of the kerneloops is that sometimes the throughput of the LAN NIC is extremly low (< 500kbit/s). I need some help as I have no idea why it is happening and where it's coming from (kernel bug? faulty h/w? config error?). As I have no idea how I can trigger this oops -- it just happens after a few hours of running -- I'll list what I'm using the machine for: it's running Debian squeeze with a custom built kernel, vanilla 2.6.32.7 (.config attached). I use this machine as a router (two NICs), and use an USB ISDN device with asterisk. A WLAN AP is running over the USB wireless stick (rt73usb + hostapd 0.6.9), which is bridged with the LAN side of the one NIC. There is also a DVB-T card in there controlled by mythtv. I tried swapping the two PCI cards (r8169 and saa7134), guessing the problem may be IRQ related, but it didn't help. I'm not experienced with the kernel programming, but I can patch and recompile my kernel to isolate the problem if somebody shows me the direction. Kind regards, Lee P.S. Keep me CC: as I'm off-list.
