kernel BUG at linux-3.4/net/core/skbuff.c:127
tcp_data_queue
tcp_rcv_established

tcp_prequeue_process
tcp_recvmsg
sock_recvmsg

Some strange findings about the DPO_RT5572_LinuxSTA_2.6.1.3_20121022
crash:
Kernel
3.4.x 64bit 3.4.x 32bit 3.8.x 64bit
openSUSE
-------------------------------------------------------------------------
12.1 works fine not tested not tested
12.2 interrupt exception works fine works fine
12.1 glibc 2.14.1
gcc 4.6
binutils 2.21
12.2 glibc 2.15
gcc 4.7
binutils 2.22
I tested with the firmware package on 12.2 / 64bit from 12.1 -> it
crashed anyway. I tested the 3.4.x kernel compiled for openSUSE
12.1/64bit on 12.2/64bit -> crash on openSUSE 12.2.
What's wrong with 3.4.x/64 bit on openSUSE 12.2? netperf only uses
glibc:
ldd `which netperf`
linux-vdso.so.1 (0x00007fff5d600000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007ff68e9b8000)
libm.so.6 => /lib64/libm.so.6 (0x00007ff68e6c0000)
libc.so.6 => /lib64/libc.so.6 (0x00007ff68e318000)
/lib64/ld-linux-x86-64.so.2 (0x00007ff68ebc0000)
Any ideas?
Thanks,
Kind regards,
Andreas
