Am I correct that all new processes die after the resume? > I don't know if it's relevant but I also enabled KMS a while back - could be > a coincidence. Disabled it now will check if it makes any difference. Kernel mode-setting is new in 2.6.30, but the bugreport shows a 2.6.29. > 0xb7fe6424 in __kernel_vsyscall () > #0 0xb7fe6424 in __kernel_vsyscall () It segfaults within vsyscall. This would mean that the kernel either select a wrong vdso for the hardware or otherwise corrupts it. Because of the used address, I would assume the sysenter vdso, which looks like this: | Dump of assembler code for function __kernel_vsyscall: | 0xAAAAA414 <__kernel_vsyscall+0>: push %ecx | 0xAAAAA415 <__kernel_vsyscall+1>: push %edx | 0xAAAAA416 <__kernel_vsyscall+2>: push %ebp | 0xAAAAA417 <__kernel_vsyscall+3>: mov %esp,%ebp | 0xAAAAA419 <__kernel_vsyscall+5>: sysenter | 0xAAAAA41b <__kernel_vsyscall+7>: nop | 0xAAAAA41c <__kernel_vsyscall+8>: nop | 0xAAAAA41d <__kernel_vsyscall+9>: nop | 0xAAAAA41e <__kernel_vsyscall+10>: nop | 0xAAAAA41f <__kernel_vsyscall+11>: nop | 0xAAAAA420 <__kernel_vsyscall+12>: nop | 0xAAAAA421 <__kernel_vsyscall+13>: nop SYSENTER_RETURN-2 aka restart point: | 0xAAAAA422 <__kernel_vsyscall+14>: jmp 0xAAAAA417 <__kernel_vsyscall+3> SYSENTER_RETURN: | 0xAAAAA424 <__kernel_vsyscall+16>: pop %ebp | 0xAAAAA425 <__kernel_vsyscall+17>: pop %edx | 0xAAAAA426 <__kernel_vsyscall+18>: pop %ecx | 0xAAAAA427 <__kernel_vsyscall+19>: ret This code has not changed in the last versions.
