[Xen-users] Problem with XEN on Tyan S2882-D 2xAMD280 16GB
Hello! We have a lot of strange Problems with Xen on Tyan S2882-D with two Dual-Core Opterons AMD280 and 16GB Corsair Memory. (K4H510438C-ZCCC) Symptom: Under high load, i.e. "make allyesconfig; make -j" of linux kernel in dom0 with allocated 16000MB of RAM crashes after a short time. (Compiler aborts) and I have to reboot the system. The strangest thing is: We have three of those systems, one is working perfektly, two others not. Identical hardware. While looking at xm dmesg i found the following on two different systems: ============== RUNNING SYSTEM ===================== Xen version 3.0.2 (root@) (gcc version 3.4.4 (Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8)) Wed May 10 00:02:16 CEST 2006 Latest ChangeSet: Sat Apr 8 12:14:27 2006 +0100 9598:1bce05ff1e52 (XEN) Physical RAM map: (XEN) 0000000000000000 - 000000000009f400 (usable) (XEN) 000000000009f400 - 00000000000a0000 (reserved) (XEN) 00000000000e0000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 00000000fbff0000 (usable) (XEN) 00000000fbff0000 - 00000000fbfff000 (ACPI data) (XEN) 00000000fbfff000 - 00000000fc000000 (ACPI NVS) (XEN) 00000000ff780000 - 0000000100000000 (reserved) (XEN) 0000000100000000 - 0000000400000000 (usable) (XEN) System RAM: 16319MB (16711228kB) (XEN) Xen heap: 9MB (10052kB) (XEN) Using scheduler: Simple EDF Scheduler (sedf) (XEN) PAE enabled, limit: 16 GB (XEN) found SMP MP-table at 000ff780 (XEN) DMI 2.3 present.

Any hints ?? Thanks, Markus _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
