Frequency of the symptom was reduced, but occurred once hr> in 2-3 days. So it is reproducible on 8.0R, too. JFYI, when I tried 8-STABLE as of May 15 the periodic hang-ups disappeared. The chip ids are 0x109a8086 and 0x108c8086 (pciconf reported them as 82573L and 82573E, added to PCI slots on the box). The hang-ups were able to be reproduced on 8.0-RELEASE. I didn't tried other boxes which had another symptom (abnormal long interval between each packet), but I will give it a try and report it, too I have no idea of what was the cause because there were a lot of changes since the release, though. -- Hiroki ----Security_Multipart(Tue_May_25_03_18_31_2010_890)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAkv6wvcACgkQTyzT2CeTzy2RWACfUdVSIcvg2tJFj25vUl3+0sI4 qJEAoJWupIbLNZ5UiIxumnUfdXdk4gfR =kuzc -----END PGP SIGNATURE----- ----Security_Multipart(Tue_May_25_03_18_31_2010_890)----
