8624.0. "ISP_BUSY error and system hangs!" by DYOSW5::WILDER (Does virtual reality get swapped?) Tue Jan 28 1997 19:17

    2 8200s, running DUNIX V4.2B The boot_reset is on, so booting the
    systems causes an init.
    
    Occassionally, when booting the systems, one will hang during boot with
    the following error messages:
    
    ips3: QLOGIC ISP1020
    camm_logger:  CAM_ERROR packet
    cam_logger:  bus 3
    isp_mailboxcomplete
    Timeout on mailbox command completion - scheduling chip reinit
    cam_logger: CAM_ERROR packet
    cam_logger:  bus 3
    isp_init
    ISP_BUSY status for mailbox operations during common init - delaying
    
    At this point the system will hang. Only a power fail will clear this
    and allow the system to reboot.
    
    I have seen this on BOTH systems, but I cannot duplicate it will. The
    "isp3" is where the internal system disk is.
    
    Has anyone seen this and/or know what causes it? Is there a patch? I
    have looked at the current patches for 4.0B, and none of them seem to
    address this problem.
    
    Thanks in advance for any help.

There is a patch for this; it must still be in the process loop.

Check with Bill Arvidson in the support group.  He's the manager
for the I/O support group and would know the patch status.

Apparently there is a patch 62 to fix this problem.  I'll be applying this 
patch in the next couple of weeks for testing......
