Hello! I don't shure I'm writing to right list, please point me to right list, if this is wrong place. And I posted this message to linux-net... Sorry! I run Linux as bridge (with ebtables), router and ipsec using super-freeswan/openswan. ipsec interface is over br interface, there are also vlan interfaces on the same eth interfaces wich are in bridge. Kernel 2.4.20 works OK, but I have kernel crash when I try to use htb qos over ipsec interfaces. So I decided to move to newer kernel. This is 2.4.28 from kernel org with openswan 1.0.8 and ebtables-brnf-8_vs_2.4.28. <http://prdownloads.sourceforge.net/ebtables/ebtables-brnf-8_vs_2.4.28.diff.gz?download> Here is kernel oops: vpn_22_203 login: Unable to handle kernel NULL pointer dereference at virtual address 00000024 d0129426 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<d0129426>] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010246 eax: 00000000 ebx: c02efb50 ecx: c02efb50 edx: cde528e0 esi: 00000000 edi: d00c7be0 ebp: d00c7be0 esp: c02efad8 ds: 0018 es: 0018 ss: 0018 Process swapper (pid: 0, stackpage=c02ef000) Stack: c02efb30 80000000 c0347560 c0211648 00000004 c02efb50 00000000 ce314804 d00c7be0 80000000 00000004 ce314804 00000000 c0211955 c0347560 c02efb50 00000004 00000000 ce314804 c02efb30 d00c7be0 80000000 d012ecf0 cdb3a9e0 Call Trace: [<c0211648>] [<d00c7be0>] [<c0211955>] [<d00c7be0>] [<d012ecf0>] [<d00cbade>] [<d00c7be0>] [<d00c7be0>] [<c0211648>] [<d00c7be0>] [<c0211955>] [<d00c7be0>] [<d00cdb00>] [<d00c7cea>] [<d00c7be0>] [<c0211995>] [<d00c7cb0>] [<d00cb899>] [<d00c7cb0>] [<d00c7cb0>] [<c0211648>] [<d00c7cb0>] [<c0211955>] [<d00c7cb0>] [<d00cdae8>] [<d00c7d2a>] [<d00c7cb0>] [<d00c7273>] [<d00c72af>] [<c0209682>] [<c022279c>] [<c0222710>] [<d00cbc2d>] [<c0222710>] [<c0211648>] [<c0222710>] [<c0211955>] [<c0222710>] [<d00cdba8>] [<c021fa90>] [<c0220f2a>] [<c0222710>] [<c021fa90>] [<c021fac6>] [<d00cbc2d>] [<c021fa90>] [<c0211648>] [<d010be20>] [<c021fa90>] [<c0211955>] [<d010be20>] [<c021fa90>] [<d00cdb48>] [<d010be20>] [<c021fa05>] [<d010be20>] [<c021fa90>] [<d010be20>] [<c021ea47>] [<c021e880>] [<d00cbb85>] [<c0211648>] [<d010be20>] [<c021e880>] [<c0211955>] [<d010be20>] [<c021e880>] [<d00cdb18>] [<c021e68c>] [<d010be20>] [<c021e880>] [<d010be20>] [<c0209c6c>] [<d010be20>] [<d010be20>] [<c0209d80>] [<c0209e9f>] [<c011af39>] [<c010a081>] [<c0106ea0>] [<c010c3b8>] [<c0106ea0>] [<c0106ec4>] [<c0106f32>] [<c0105000>] Code: 8b 46 24 39 42 60 77 07 ba 01 00 00 00 eb e9 57 52 e8 f4 8c >>EIP;

Could you look to this and give me an idea where is problem? I.e. this is bridge or ipsec problem or something else? Thank you!
