It is:
[ 156.094049] sys_vm86old called by monitor-get-edi [ 156.243660] sys_vm86old called by monitor-get-edi [ 285.698333] sys_vm86old called by X [ 285.699408] sys_vm86old called by X [ 285.699813] sys_vm86old called by X
any chance the specific function that is invoked is not implemented? Because at least X apparently does not always fail video BIOS call - how can I catch which calls were successful and which failed? I understand return path sys_vm86old is rather non-standard. [unhandled content-type:application/pgp-signature] | |
