This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigCD3A6D7F746A74CEB43CA721 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Since last upgrade, I see much more CPU time "eated" by interrupts (at least 10% cpu in top) (see http://dgeo.perso.ec-marseille.fr/cpu-week.png) The server behave correctly (Or seems to=E2=80=A6), and high interrupt nu= mber seems to come from bce cards (source: systat -vmstat) I just upgraded from "RELENG_7 Mon Sep 8 12:33:06 CEST 2008" to "RELENG_7_1 Sat Nov 29 16:20:35 CET 2008" We have the same machine (dell PE 1950) which have not been upgraded (production use - the two machine are carp(4)-redundant) I don't know if it is related to "SVN rev 184826 on 2008-11-10 22:40:16Z by delphij" patch to sys/dev/bce/if_bce.c If I can help debugging something=E2=80=A6 These are production machines,= but I may test patches or ? on the faulty system. Some clues: Under the very same load (carp interfaces down on other machine), vmstat shows: for newer system: procs memory page disk faults cpu r b w avm fre flt re pi po fr sr mf0 in sy cs us sy id 0 1 1 4806M 460M 649 0 0 0 582 2 0 21770 1270 13653 1 15 85 and for older: procs memory page disk faults cpu r b w avm fre flt re pi po fr sr mf0 in sy cs us sy id 0 1 0 3694M 414M 236 0 0 0 199 17 0 286 317 386 1 1 97 bce-related part of dmesg for the newer system: bce0: <Broadcom NetXtreme II BCM5708 1000Base-T (B2)> mem 0xf4000000-0xf5ffffff irq 16 at device 0.0 on pci9 miibus0: <MII bus> on bce0 bce0: Ethernet address: 00:15:c5:f1:56:f4 bce0: [ITHREAD] bce0: ASIC (0x57081020); Rev (B2); Bus (PCI-X, 64-bit, 133MHz); F/W (0x02090105); Flags( SPLT MFW MSI ) bce1: <Broadcom NetXtreme II BCM5708 1000Base-T (B2)> mem 0xf8000000-0xf9ffffff irq 16 at device 0.0 on pci5 miibus1: <MII bus> on bce1 bce1: Ethernet address: 00:15:c5:f1:56:f2 bce1: [ITHREAD] bce1: ASIC (0x57081020); Rev (B2); Bus (PCI-X, 64-bit, 133MHz); F/W (0x02090105); Flags( SPLT MFW MSI ) And on the older system: bce0: <Broadcom NetXtreme II BCM5708 1000Base-T (B2)> mem 0xf4000000-0xf5ffffff irq 16 at device 0.0 on pci9 miibus0: <MII bus> on bce0 bce0: Ethernet address: 00:15:c5:f1:6a:47 bce0: [ITHREAD] bce0: ASIC (0x57081020); Rev (B2); Bus (PCI-X, 64-bit, 133MHz); F/W (0x02090105); Flags( MFW MSI ) bce1: <Broadcom NetXtreme II BCM5708 1000Base-T (B2)> mem 0xf8000000-0xf9ffffff irq 16 at device 0.0 on pci5 miibus1: <MII bus> on bce1 bce1: Ethernet address: 00:15:c5:f1:6a:45 bce1: [ITHREAD] bce1: ASIC (0x57081020); Rev (B2); Bus (PCI-X, 64-bit, 133MHz); F/W (0x02090105); Flags( MFW MSI ) --=20 Geoffroy Desvernay Ecole Centrale de Marseille --------------enigCD3A6D7F746A74CEB43CA721 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkk1BqAACgkQGbFYzwF8gKpr8wCePV+QlUMCTLLsXDkXUbloma/j 9XEAnjSlSox0B1leCuGRuX8lsb8EyDtU =ulkO -----END PGP SIGNATURE----- --------------enigCD3A6D7F746A74CEB43CA721--
