>Description:
In the file sys/pccard/pcic_pci.c version 1.110 line 746 it is attempting to set a 4 byte register, however is calls pci_write_config with a length of 1 so the upper 3 bytes are not modified.
>How-To-Repeat:
>Fix:
Here is a patch to version 1.110 of sys/pccard/pcic_pci.c
***************
*** 743,749 ****
syscntl |= TI113X_SYSCNTL_INTRTIE;
}
syscntl &= ~TI113X_SYSCNTL_SMIENB;
! pci_write_config(dev, TI113X_PCI_SYSTEM_CONTROL, syscntl, 1);
}
if (cardcntl & TI113X_CARDCNTL_RING_ENA)
printf("[ring enable]");
