Tamas Csillag, could you please test for this in Precise server via http://releases.ubuntu.com/12.04.2/ and advise is this still reproducible?
** Description changed: - After upgrading from linux-image-2.6.32-43-server to linux-image-2.6.32-45-server, we started experiencing intermittent lockups on one of our servers: TCP connections frozen, no pings for 5-10 minutes, everything fine afterwards. Issue happens 1-3 times a day, usually under loads over 2.0. - Server is a dedicated bacula server, usually no significant load during the day. - Nothing in dmesg or syslog. - - Based on the Ubuntu kernel changelog, I'd guess network TSO or a SCSI problem. - As this is not a full-time critical server, we can do some testing. - - Regards, - Tamas - - - 00:00.0 Host bridge: Intel Corporation 3200/3210 Chipset DRAM Controller (rev 01) - 00:01.0 PCI bridge: Intel Corporation 3200/3210 Chipset Host-Primary PCI Express Bridge (rev 01) - 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 02) - 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 02) - 00:1c.5 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 6 (rev 02) - 00:1d.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02) - 00:1d.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02) - 00:1d.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02) - 00:1d.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02) - 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 92) - 00:1f.0 ISA bridge: Intel Corporation 82801IR (ICH9R) LPC Interface Controller (rev 02) - 00:1f.2 IDE interface: Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 4 port SATA Controller [IDE mode] (rev 02) - 01:00.0 PCI bridge: Intel Corporation 80333 Segment-A PCI Express-to-PCI Express Bridge - 01:00.2 PCI bridge: Intel Corporation 80333 Segment-B PCI Express-to-PCI Express Bridge - 02:0e.0 RAID bus controller: Dell PowerEdge Expandable RAID controller 5 - 04:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03) - 05:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 21) - 06:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 21) - 07:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI ES1000 (rev 02) + After upgrading from linux-image-2.6.32-43-server to linux- + image-2.6.32-45-server, we started experiencing intermittent lockups on + one of our servers: TCP connections frozen, no pings for 5-10 minutes, + everything fine afterwards.
