It only happens when I send more than a small amount of data from my OSX86 system to my linux server. I can download files from the linux server without any problems, but if I begin to upload anything it will kernel panic the system in 2 seconds or less. I haven't had any problem with regular SSH sessions, but if I send files using scp or SMB the linux kernel panics almost immediately. My OSX86 system is using an Asus Striker Extreme with onboard Marvell 88E1116 Gigabit Ethernet 10/100/1000Mbps and the driver is nForcEthernetDriver.kext which uses forcedeth. -rwxr-xr-x 1 root wheel 131148 Feb 22 2008 nForcEthernetDriver.kext/Contents/MacOS/forcedeth On Tue, Mar 10, 2009 at 09:10:13PM -0400, Christian wrote: > Hello, > > I keep getting kernel panics on my system with output similar to this: > > skb_over_panic: text:fffffffff80456cc4 len:2580 put:2580 > head:ffff9900bf18a000 data:ffff8800bf18a010 tail:0xa end:0x640 dev:eth0 > --------[ cut here ] ---------- > kernel BUG at net/core/skbuff.c:124!xt:ffffffff80456cc4 len:2580 > put:2580 head:ffff8800bf18a000 data:ffff8800bf18a010 tail:0xa > invalid opcode: 0000 [#1] SMP > last sysfs file: /sys/devices/pci0000:00/0000:00:1f.0/resource > CPU 5 > Modules linked in nvidia(P) > Pid: 0, comm: swapper Tainted: P 2.6.28.7 #3 > RIP: 0010:[] [] skb_put+0x7a/0x89 > RSP: 0018:ffff8801bf9b3dd0 EFLAGS: 00010282 > > (I copied this output by hand so there may be a typo or two) > > Linux server1 2.6.28.7 #3 SMP Mon Mar 9 20:04:12 EDT 2009 x86_64 > Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux > > Before this my kernel was 2.6.27.5 and I was still getting the same > panics. > > eth0: RTL8168c/8111c at 0xffffc20000042000, 00:23:54:ed:7f:a6, XID > 3c4000c0 IRQ 18 > r8169: eth0: link up > > 00:00.0 Host bridge: Intel Corporation QuickPath Architecture I/O Hub to > ESI Port (rev 12) > 00:01.0 PCI bridge: Intel Corporation QuickPath Architecture I/O Hub PCI > Express Root Port 1 (rev 12) > 00:03.0 PCI bridge: Intel Corporation QuickPath Architecture I/O Hub PCI > Express Root Port 3 (rev 12) > 00:07.0 PCI bridge: Intel Corporation QuickPath Architecture I/O Hub PCI > Express Root Port 7 (rev 12) > 00:10.0 PIC: Intel Corporation QuickPath Interconnect Physical and Link > Layer Registers Port 0 (rev 12) > 00:10.1 PIC: Intel Corporation QuickPath Interconnect Routing and > Protocol Layer Registers Port 0 (rev 12) > 00:13.0 PIC: Intel Corporation QuickPath Architecture I/O Hub I/OxAPIC > Interrupt Controller (rev 12) > 00:14.0 PIC: Intel Corporation QuickPath Architecture I/O Hub System > Management Registers (rev 12) > 00:14.1 PIC: Intel Corporation QuickPath Architecture I/O Hub GPIO and > Scratch Pad Registers (rev 12) > 00:14.2 PIC: Intel Corporation QuickPath Architecture I/O Hub Control > Status and RAS Registers (rev 12) > 00:14.3 PIC: Intel Corporation QuickPath Architecture I/O Hub Throttle > Registers (rev 12) > 00:1a.0 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB > UHCI Controller #4 > 00:1a.1 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB > UHCI Controller #5 > 00:1a.2 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB > UHCI Controller #6 > 00:1a.7 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB2 > EHCI Controller #2 > 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio > Controller > 00:1c.0 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express > Port 1 > 00:1c.2 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express > Port 3 > 00:1c.3 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express > Port 4 > 00:1c.4 PCI bridge: Intel Corporation 82801JI (ICH10 Family) PCI Express > Port 5 > 00:1d.0 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB > UHCI Controller #1 > 00:1d.1 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB > UHCI Controller #2 > 00:1d.2 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB > UHCI Controller #3 > 00:1d.7 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB2 > EHCI Controller #1 > 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 90) > 00:1f.0 ISA bridge: Intel Corporation 82801JIR (ICH10R) LPC Interface > Controller > 00:1f.2 IDE interface: Intel Corporation 82801JI (ICH10 Family) 4 port > SATA IDE Controller > 00:1f.3 SMBus: Intel Corporation 82801JI (ICH10 Family) SMBus Controller > 00:1f.5 IDE interface: Intel Corporation 82801JI (ICH10 Family) 2 port > SATA IDE Controller > 02:00.0 VGA compatible controller: nVidia Corporation G72 [GeForce 7300 > LE] (rev a1) > 04:00.0 SATA controller: JMicron Technologies, Inc.
