Lately we got a machine with new HW from Intel. CPU is Intel Core2 Duo E6850 3GHz with 2GB of RAM. Motherboard is Intel DG33BU with G33 chipset. After long fight with kernel crashes on different things, we figured out that if the multicore is disabled in bios, everything is ok and machine is running good. No kernel crashes no problems, but with one core only. This small table will maybe explain: Cores - kernel - state 2 - nonsmp or smp - crash 1 - smp or nonsmp - ok All crashes have been different (swaper, rcu, irq, init.....) or we just got internal gcc compiler error while compiling kernel/glibc/.... and the machine was frozen. Please can somebody advise what to do to identify that problem more precisely. (debug kernel options?) Our immpresion - ICH9 & ICH9R support in kernel is bad... sorry to say.. lspci: 00:00.0 Host bridge: Intel Corporation DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation Integrated Graphics Controller (rev 02) 00:03.0 Communication controller: Intel Corporation MEI Controller (rev 02) 00:1a.0 USB Controller: Intel Corporation USB UHCI Controller #4 (rev 02) 00:1a.1 USB Controller: Intel Corporation USB UHCI Controller #5 (rev 02) 00:1a.2 USB Controller: Intel Corporation USB UHCI Controller #6 (rev 02) 00:1a.7 USB Controller: Intel Corporation USB2 EHCI Controller #2 (rev 02) 00:1c.0 PCI bridge: Intel Corporation PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation PCI Express Port 2 (rev 02) 00:1c.2 PCI bridge: Intel Corporation PCI Express Port 3 (rev 02) 00:1c.3 PCI bridge: Intel Corporation PCI Express Port 4 (rev 02) 00:1c.4 PCI bridge: Intel Corporation PCI Express Port 5 (rev 02) 00:1d.0 USB Controller: Intel Corporation USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation USB UHCI Controller #3 (rev 02) 00:1d.7 USB Controller: Intel Corporation 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 LPC Interface Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 4 port SATA IDE Controller (rev 02) 00:1f.3 SMBus: Intel Corporation SMBus Controller (rev 02) 00:1f.5 IDE interface: Intel Corporation 2 port SATA IDE Controller (rev 02) 02:00.0 IDE interface: Marvell Technology Group Ltd. 88SE6101 single-port PATA133 interface (rev b1) 06:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
