FS#3193 - official bird2 build on ipq806x doesn't start and has bus error
Hi all,
I am running bird2 on Netgear R7800 for OSPF routing but it doesn’t start. Following are error messages I got:
# bird -c /etc/bird.conf -d Bus error # logread Sat Jun 20 12:24:09 2020 daemon.info bird: Started Sat Jun 20 12:24:09 2020 kern.err kernel: [572809.062848] Alignment trap: not handling instruction f44c0a1f at [<0006bb88>] Sat Jun 20 12:24:09 2020 kern.alert kernel: [572809.062907] Unhandled fault: alignment exception (0x801) at 0x017c9634 Sat Jun 20 12:24:09 2020 kern.alert kernel: [572809.069111] pgd = d7668000 Sat Jun 20 12:24:09 2020 kern.alert kernel: [572809.075597] [017c9634] *pgd=5c0c6835, *pte=5ad3475f, *ppte=5ad34c7f # dmesg [571421.877597] Alignment trap: not handling instruction f44c0a1f at [<0006bb88>] [571421.877645] Unhandled fault: alignment exception (0x801) at 0x0111b624 [571421.883832] pgd = dc258000 [571421.890385] [0111b624] *pgd=5e63a835, *pte=5c72975f, *ppte=5c729c7f

}
# OSPF example, both OSPFv2 and OSPFv3 are supported
protocol ospf v2 ospf4 {

};
}
This issue can be reproduced with the latest OpenWrt release 19.07.3, but it has been there for a long time.
A custom build of bird2 package with OpenWRT SDK doesn’t have this issue.
I am not sure this is the right place to report this issue. Could anyone help with this?
