Willy, The machine is a virtual machine on an VMware ESX 3.0.1 host. /proc/cpuinfo shows two of these: Dual model : 15 model name : Intel(R) Xeon(R) CPU E5345 @ 2.33GHz stepping : 8 cpu MHz : 2333.014 cache size : 64 KB It has 864MB of memory. .config is at: http://v.iki.fi/~vherva/tmp/2.4.35-config The kernel is plain vanilla 2.4.35 from kernel.org, no patches. gcc 2.96-129: cat /proc/version Linux version 2.4.35 (root) (gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-129.7.2)) #1 SMP Thu Aug 9 10:35:37 EEST 2007 Memory is ECC. The server is HP Proliant ML370 with 82801BA/CA/DB/EB chipset. I've had my share of chipset bugs with older Via chipsets, but I think it's very likely in this case. This could very well be a VMware bug, but I wanted to know if this rings bells for someone. -- v -- v@iki.fi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
