Hello Jeremy and others, I friend of mine is trying to install x86_64 Fedora 11 Xen PV domU on CentOS 5.4 x86_64 dom0. He's getting a kernel crash.. so I was wondering if you've seen this one before. A couple of kernel boot/crash logs: http://v6.fi/misc/f11_64_kernel.debug2.txt http://v6.fi/misc/f11_64_kernel.debug4.txt (early) Kernel command line: root=/dex/xvda1 ro earlyprintk=xen (early) Initializing CPU#0 (early) invalid opcode: 0000 [#1] (early) SMP (early) (early) last sysfs file: (early) CPU 0 (early) (early) Modules linked in:(early) (early) Pid: 0, comm: swapper Not tainted 2.6.29.4-167.fc11.x86_64 #1 (early) RIP: e030:[<ffffffff81397963>] (early) [<ffffffff81397963>] xsave_cntxt_init+0xba/0x199 [root@dom0 RH]# gdb vmlinux (gdb) x/i 0xffffffff81397963 0xffffffff81397963 <xsave_cntxt_init+186>: xsetbv (gdb) x/60i xsave_cntxt_init 0xffffffff813978a9 <xsave_cntxt_init>: push %rbp 0xffffffff813978aa <xsave_cntxt_init+1>: mov %rsp,%rbp 0xffffffff813978ad <xsave_cntxt_init+4>: push %r14 0xffffffff813978af <xsave_cntxt_init+6>: push %r13 0xffffffff813978b1 <xsave_cntxt_init+8>: push %r12 0xffffffff813978b3 <xsave_cntxt_init+10>: push %rbx 0xffffffff813978b4 <xsave_cntxt_init+11>: sub $0x10,%rsp 0xffffffff813978b8 <xsave_cntxt_init+15>: callq 0xffffffff81011000 <mcount> 0xffffffff813978bd <xsave_cntxt_init+20>: lea -0x24(%rbp),%rbx 0xffffffff813978c1 <xsave_cntxt_init+24>: lea -0x28(%rbp),%r12 0xffffffff813978c5 <xsave_cntxt_init+28>: lea -0x2c(%rbp),%r13 0xffffffff813978c9 <xsave_cntxt_init+32>: lea -0x30(%rbp),%r14 0xffffffff813978cd <xsave_cntxt_init+36>: movl $0xd,-0x24(%rbp) 0xffffffff813978d4 <xsave_cntxt_init+43>: movl $0x0,-0x2c(%rbp) 0xffffffff813978db <xsave_cntxt_init+50>: mov %rbx,%rdi 0xffffffff813978de <xsave_cntxt_init+53>: mov %r12,%rsi 0xffffffff813978e1 <xsave_cntxt_init+56>: mov %r13,%rdx 0xffffffff813978e4 <xsave_cntxt_init+59>: mov %r14,%rcx 0xffffffff813978e7 <xsave_cntxt_init+62>: callq *0x1f24b3(%rip) # 0xffffffff81589da0 <pv_cpu_ops+224> 0xffffffff813978ed <xsave_cntxt_init+68>: mov -0x30(%rbp),%eax 0xffffffff813978f0 <xsave_cntxt_init+71>: mov -0x24(%rbp),%esi 0xffffffff813978f3 <xsave_cntxt_init+74>: shl $0x20,%rax 0xffffffff813978f7 <xsave_cntxt_init+78>: lea (%rax,%rsi,1),%rsi 0xffffffff813978fb <xsave_cntxt_init+82>: mov %rsi,%rax 0xffffffff813978fe <xsave_cntxt_init+85>: mov %rsi,0x4357ab(%rip) # 0xffffffff817cd0b0 <pcntxt_mask> 0xffffffff81397905 <xsave_cntxt_init+92>: and $0x3,%eax 0xffffffff81397908 <xsave_cntxt_init+95>: cmp $0x3,%rax 0xffffffff8139790c <xsave_cntxt_init+99>: je 0xffffffff81397920 <xsave_cntxt_init+119> 0xffffffff8139790e <xsave_cntxt_init+101>: mov $0xffffffff814ca823,%rdi 0xffffffff81397915 <xsave_cntxt_init+108>: xor %eax,%eax 0xffffffff81397917 <xsave_cntxt_init+110>: callq 0xffffffff813a95be <printk> 0xffffffff8139791c <xsave_cntxt_init+115>: ud2a 0xffffffff8139791e <xsave_cntxt_init+117>: jmp 0xffffffff8139791e <xsave_cntxt_init+117> ---Type <return> to continue, or q <return> to quit--- 0xffffffff81397920 <xsave_cntxt_init+119>: testb $0x4,0x26a700(%rip) # 0xffffffff81602027 <boot_cpu_data+39> 0xffffffff81397927 <xsave_cntxt_init+126>: movq $0x3,0x43577e(%rip) # 0xffffffff817cd0b0 <pcntxt_mask> 0xffffffff81397932 <xsave_cntxt_init+137>: je 0xffffffff81397966 <xsave_cntxt_init+189> 0xffffffff81397934 <xsave_cntxt_init+139>: orq $0x40000,0x423721(%rip) # 0xffffffff817bb060 <mmu_cr4_features> 0xffffffff8139793f <xsave_cntxt_init+150>: callq *0x1f23ab(%rip) # 0xffffffff81589cf0 <pv_cpu_ops+48> 0xffffffff81397945 <xsave_cntxt_init+156>: mov %eax,%edi 0xffffffff81397947 <xsave_cntxt_init+158>: or $0x40000,%edi 0xffffffff8139794d <xsave_cntxt_init+164>: callq *0x1f23a5(%rip) # 0xffffffff81589cf8 <pv_cpu_ops+56> 0xffffffff81397953 <xsave_cntxt_init+170>: mov 0x435756(%rip),%rax # 0xffffffff817cd0b0 <pcntxt_mask> 0xffffffff8139795a <xsave_cntxt_init+177>: xor %ecx,%ecx 0xffffffff8139795c <xsave_cntxt_init+179>: mov %rax,%rdx 0xffffffff8139795f <xsave_cntxt_init+182>: shr $0x20,%rdx 0xffffffff81397963 <xsave_cntxt_init+186>: xsetbv 0xffffffff81397966 <xsave_cntxt_init+189>: movl $0xd,-0x24(%rbp) 0xffffffff8139796d <xsave_cntxt_init+196>: movl $0x0,-0x2c(%rbp) 0xffffffff81397974 <xsave_cntxt_init+203>: mov %rbx,%rdi 0xffffffff81397977 <xsave_cntxt_init+206>: mov %r12,%rsi 0xffffffff8139797a <xsave_cntxt_init+209>: mov %r13,%rdx 0xffffffff8139797d <xsave_cntxt_init+212>: mov %r14,%rcx 0xffffffff81397980 <xsave_cntxt_init+215>: callq *0x1f241a(%rip) # 0xffffffff81589da0 <pv_cpu_ops+224> 0xffffffff81397986 <xsave_cntxt_init+221>: mov $0xffffffff817cd0c0,%rsi 0xffffffff8139798d <xsave_cntxt_init+228>: xor %eax,%eax 0xffffffff8139798f <xsave_cntxt_init+230>: mov $0xc,%ecx 0xffffffff81397994 <xsave_cntxt_init+235>: mov %rsi,%rdi 0xffffffff81397997 <xsave_cntxt_init+238>: mov -0x28(%rbp),%ebx 0xffffffff8139799a <xsave_cntxt_init+241>: rep stos %eax,%es:(%rdi) 0xffffffff8139799c <xsave_cntxt_init+243>: mov 0x43570d(%rip),%rax # 0xffffffff817cd0b0 <pcntxt_mask> (gdb) -- Pasi -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
