I can reproduce it immediately, and reliably, just by issuing an ssh command (as a normal user). Hardware: Pentium III 933 w/512 MB RAM Red Hat 7.1+ updates I have 2 eepro 100 cards and am running an iptables firewall. The condition exists in 2.4.15-pre1 and -pre2. I have not seen this before (2.4.14 is fine) Tonight I compiled 2.4.15-pre2 and ran dbench for awhile, with good results. Then I tried the simple "ssh "cmd that locked up -pre1 - sure enough, it locked up the system again - Here is the hand-copied, decoded oops: ksymoops 2.4.3 on i686 2.4.15-pre2. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.15-pre2/ (default) -m /boot/System.map (specified) c01b8345 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010293 eax: 000005dc ebx: df0f7de0 ecx: df0e1000 edx: 0000000e esi: df96bdec edi: 00000000 ebp: d793b2a0 esp: da64bcf8 ds: 0018 es: 0018 ss: 0018 Process ssh (pid:2028, stackpage=da64b000) Stack: 00000003 c01b82b0 c01af49b c0294838 00000000 df0e1000 00000003 c01b82b0 c01af4d2 df0d7de0 00000000 c0294838 df96b690 00000286 0001e9c0 00000286 df0e1000 de4297a0 00000000 dfd8aee0 c01b7269 00000002 00000003 df0d7de0 Call Trace: [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] [] Code: 0f b6 87 c6 02 00 00 31 d2 3c 02 74 0a fe c8 75 0b f6 45 20 >>EIP; c01b8344 <===== Trace; c01b82b0 Trace; c01af49a Trace; c01b82b0 Trace; c01af4d2 Trace; c01b7268 Trace; c01b82b0 Trace; c01abec8 Trace; c01c9d5e Trace; c01c5242 Trace; c01c755a Trace; c015fcb6 Trace; c01c95f6 Trace; c01d42c2 Trace; c01a3df6 Trace; c01a2fce Trace; c01a3a26 Trace; c01211b0 Trace; c01a3a7c Trace; c01a4790 Trace; c011d34a Trace; c0106cfa Code; c01b8344 00000000 <_EIP>: Code; c01b8344 <===== 0: 0f b6 87 c6 02 00 00 movzbl 0x2c6(%edi),%eax <===== Code; c01b834a 7: 31 d2 xor %edx,%edx Code; c01b834c 9: 3c 02 cmp $0x2,%al Code; c01b834e b: 74 0a je 17 <_EIP+0x17> c01b835a Code; c01b8350 d: fe c8 dec %al Code; c01b8352 f: 75 0b jne 1c <_EIP+0x1c> c01b8360 Code; c01b8354 11: f6 45 20 00 testb $0x0,0x20(%ebp) <0>Kernel panic: Aiee, killing interrupt handler! - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
