The problem is that with every kernel (> 2.6.32.1 including 2.6.24 RCs) will just hang with "too much" console activity. Sometimes (well most of the time) boot msg is too much. When I can boot into the kernel, generating a lots of cosole out it will hang, no oops, no more console/network. Generating with the same way through ssh will not hang the domU. When I reverse the following patch, things work as before, tried this with 2.6.23.14 and 2.6.14-rc8. But I don't have the knowledge to understand the reason behind this. BTW, I am not subscribed. --- a/include/xen/interface/vcpu.h +++ b/include/xen/interface/vcpu.h @@ -160,8 +160,9 @@ struct vcpu_set_singleshot_timer { */ #define VCPUOP_register_vcpu_info 10 /* arg == struct vcpu_info */ struct vcpu_register_vcpu_info { - uint32_t mfn; /* mfn of page to place vcpu_info */ - uint32_t offset; /* offset within page */ + uint64_t mfn; /* mfn of page to place vcpu_info */ + uint32_t offset; /* offset within page */ + uint32_t rsvd; /* unused */ }; #endif /* __XEN_PUBLIC_VCPU_H__ */ I am running Xen 3.1.2 PAE # uname -a Linux builder 2.6.24-rc8 #2 SMP Thu Jan 17 16:37:19 CET 2008 i686 AMD Athlon(tm) X2 Dual Core Processor BE-2300 AuthenticAMD GNU/Linux # cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 107 model name : AMD Athlon(tm) X2 Dual Core Processor BE-2300 stepping : 1 cpu MHz : 1899.930 cache size : 512 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu tsc msr pae mce cx8 mca cmov pat pse36 clflush mmx fxsr sse sse2 ht nx mmxext fxsr_opt lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch ts fid vid ttp tm stc 100mhzsteps bogomips : 3829.72 clflush size : 64 processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 107 model name : AMD Athlon(tm) X2 Dual Core Processor BE-2300 stepping : 1 cpu MHz : 1899.930 cache size : 512 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu tsc msr pae mce cx8 mca cmov pat pse36 clflush mmx fxsr sse sse2 ht nx mmxext fxsr_opt lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch ts fid vid ttp tm stc 100mhzsteps bogomips : 3829.72 clflush size : 64
