-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Next time I promise to finish the report before hitting send. I'm using a Gentoo Linux system with the vanilla 2.4.28 sources installed. The attached config file is what I'm using. appletalk.o now has a dependency it didn't have in 2.4.26, which are the modules psnap.o and p8022.o, which I can't find how to disable. If I start netatalk, it modprobes appletalk.o, which loads psnap.o and p8022.o. If I then stop appletalk, it removes appletalk.o (which works) and then psnap.o and p8022.o (which kernel panics). I can also get the kernel panic by modprobing p8022.o and then rmmodding it. The kernel panic is as follows: Oops: 0000 CPU: 0 EIP: 0010:[] Not tainted EFLAGS: 00010286 eax: 00000004 ebx: cc84a3c0 ecx: 41b75c48 edx: c1363b28 esi: cb6d65e0 edi: 00000400 ebp: 00013b56 esp: c030bf18 ds: 0018 es: 0018 ss: 0018 Process swapper (pid: 0. stackpage=c030b000) Stack: c030bfa0 0000e401 cc841cfd cbcbb400 00000000 00000040 c0238623 cb6d65e0 ~ c0324d6c c0324ca8 00013b56 00000046 c0238734 c0324ca8 c030bf54 0000012c ~ 00000001 c0324b70 fffffffb c011c775 c0324b70 c03249a0 00000005 c134ec60 Call Trace: [] [] [] [] [] ~ [] [] [] [] [] [] Code: 66 39 3b 74 60 8b 5b 10 85 db 75 f4 85 d2 74 36 8b 7a 0c 85 ~ <0>Kernel panic: Aiee, killing interrupt hander! In interrupt handler - not syncing This is a problem because we can't shutdown the machine without this occurring. It seems that if we disable ipchains in the kernel, it goes away. It also occurs with the 2.4.27 kernel. A change we see is in the linux-2.4.28/net/Makefile mod-subdirs := ipv4/netfilter ipv6/netfilter ipx irda bluetooth atm netlink sched core sctp 802 whereas 2.4.26 has: mod-subdirs := ipv4/netfilter ipv6/netfilter ipx irda bluetooth atm netlink sched core sctp This also happens on a number of other machines; mainly RedHat 7.3 machines with this kernel. I'm trying to get a ksymoops now, if I get it to work, I'll reply to this post. You can see an image of the kernel panic (if such things excite you) at: http://schnecke.bombcar.com/random/kernelpanic.jpg Note that there is a short delay between removing the module and the panic. You can also get the panic by removing appletalk, (which works) and then removing psnap and waiting a few seconds. Thank you! - -Tom Dickson Tom Dickson wrote: | I've attached the config file used to compile the vanilla 2.4.28 kernel | that produces the following panic: | -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFBt2Ew2dxAfYNwANIRApVUAJ9IfJH7PJZLMsS8kidCD4myMyuVrgCdH2HP BFEJHz1RlLf9k3hAbBX1FLk= =7kKd -----END PGP SIGNATURE-----
