Prior to 2.6.33, I was running 2.6.31.12 with essentially the same config. The libc6 update to 2.10.2-6 changed things on the c3750. Prior to the update, expect would hang several times running the acats testsuite. After the update, this was fixed. However, the above problem was introduced, or became more frequent. I have the feeling that Helge's patch helps (possible resolves) the minifail bug. Dave -- J. David Anglin dave.anglin@nrc-cnrc.gc.ca National Research Council of Canada (613) 990-0752 (FAX: 952-6602)
