These crashes seem related to networking, because they happen when trying to access some hosts. Now, the system crashes (reproducible) when attempting a TCP connection to wwwkeys.eu.pgp.net from a masqueraded System (running Linux 2.2.19) - it doesn't crash when trying to connect from the Gateway itself. After such a crash, the system seems really dead; I've to fetch the Oops via a serial line. Here's the decoded Oops from clean Linux 2.4.6: -------------------------------- Unable to handle kernel paging request at virtual address 0100e018 c01268a2 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[] Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010246 eax: 0100e000 ebx: 00000000 ecx: 0100e000 edx: 00000000 esi: c068c470 edi: c0ce7a70 ebp: 00000050 esp: c021dde0 ds: 0018 es: 0018 ss: 0018 Process swapper (pid: 0, stackpage=c021d000) Stack: c0191ebd 00000100 c068c470 c01924a3 c068c470 c068c470 c008c800 c06550b0 c008c800 fffffffa c0194f3d c068c470 00000020 c0df9770 c068c470 c06550b0 c01983dd c068c470 c068c470 00000000 00000004 c01a2d60 c01a2ded c068c470 Call Trace: [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] Code: 8b 41 18 85 c0 7c 11 ff 49 14 0f 94 c0 84 c0 74 07 89 c8 e8 >>EIP; c01268a2 <__free_pages+2/20> <===== Trace; c0191ebd Trace; c01924a3 Trace; c0194f3d Trace; c01983dd Trace; c01a2d60 Trace; c01a2ded Trace; c019a6c7 Trace; c01a0400 Trace; c01a2d32 Trace; c01a2d60 Trace; c01a044a Trace; c019a6c7 Trace; c01905dc Trace; c01a03a4 Trace; c01a0400 Trace; c019f630 Trace; c019f7b9 Trace; c019f630 Trace; c019a6c7 Trace; c019f476 Trace; c019f630 Trace; c019553d Trace; c011416f Trace; c010807d Trace; c0105140 Trace; c0106c40 Trace; c0105140 Trace; c0105163 Trace; c01051c8 Trace; c0105000 <_stext+0/0> Code; c01268a2 <__free_pages+2/20> 00000000 <_EIP>: Code; c01268a2 <__free_pages+2/20> <===== 0: 8b 41 18 mov 0x18(%ecx),%eax <===== Code; c01268a5 <__free_pages+5/20> 3: 85 c0 test %eax,%eax Code; c01268a7 <__free_pages+7/20> 5: 7c 11 jl 18 <_EIP+0x18> c01268ba <__free_pages+1a/20> Code; c01268a9 <__free_pages+9/20> 7: ff 49 14 decl 0x14(%ecx) Code; c01268ac <__free_pages+c/20> a: 0f 94 c0 sete %al Code; c01268af <__free_pages+f/20> d: 84 c0 test %al,%al Code; c01268b1 <__free_pages+11/20> f: 74 07 je 18 <_EIP+0x18> c01268ba <__free_pages+1a/20> Code; c01268b3 <__free_pages+13/20> 11: 89 c8 mov %ecx,%eax Code; c01268b5 <__free_pages+15/20> 13: e8 00 00 00 00 call 18 <_EIP+0x18> c01268ba <__free_pages+1a/20> n Kernel panic: Aiee, killing interrupt handler! 1 warning issued.
