9563.0. "apecs_read_io_port after a hang..." by PANTER::AUBERT () Mon Apr 21 1997 06:35

    A customer of mine has a problem on an AlphaStation 250 4/266:
    
    For an unknown reason (probably AFS), the system hang. Then the halt
    button is pressed and the >>> appears. An init command is issued and
    the machine starts to boot (auto_action BOOT) until it detects and
    (load the driver) for the fddi interface and then crash with the
    following:
    
    fta0 DEC DEFPA FDDI Module, Hardware Revision 0
    apecs_read_io_port: illegal handle 0x0
    panic (cpu 0): apecs_read_io_port
    
    At that time, the only way to reboot the system is to switch it OFF
    then ON. It seems that the initial hang is leaving the fddi in an
    active state and when rebooting a leftover interrupt is causing the
    apecs_read_io_port 's error...
    
    Is this a Firmware problem ? (I have revision 6.3)
    
    The configuration is as follows:
    
    Digital UNIX V3.2C  (Rev. 148)
    physical memory = 256.00 megabytes
    AlphaStation 250 4/266 system
    Firmware revision: 6.3

    Any answers will be welcomed.
