Description

The test case test08 always failed with TIMED_OUT. The end of the journal is:
stdout|

This problem was observed on T2000, X4150 and X2200 M2 when testing the e1000g driver and the bnx driver. The systems were bfu'ed to the latest bits (e.g. daily.0820-nd) from
snv_96.
1) I've reproduced it on X2200M2 with nge and bnx of the bfu from /ws/onv.eng/export/home/nightly/snv_97
2) During case test08, we got two error messages in system log:
dlmgmtd[100017]: [ID 498274 daemon.warning] dlmgmt_post_sysevent(2625) failed: I/O error
Sep 3 19:27:52 airvoice devfsadmd[100164]: [ID 639486 daemon.error] failed to log event: I/O error
3) And after test08 timeout, system hang if we invoke "ifconfig -a" command.
ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
nge0: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 2
inet 10.13.30.128 netmask ffffff00 broadcast 10.13.30.255
(...no response from here)
The test08 is a vlan test. After some investigation, we found the timeout is caused by ifconfig cmd hung when trying to plumb vlan interface. Please see the comments.
Hope more suggestions from the kernel team.
Thanks
