I heard the problem like that happens on IBM ThinkPad 230Cs. Please
try the following modification to sio.c
failures[0] = inb(iobase + com_cfcr) - CFCR_8BITS;
failures[1] = inb(iobase + com_ier) - IER_ETXRDY;
failures[2] = inb(iobase + com_mcr) - mcr_image;
if (idev->id_irq != 0)
failures[3] = isa_irq_pending(idev) ? 0 : 1;
+ #ifdef TP230
+ /*
+ * Following line(outb()) is only for IBM ThinkPad 230Cs
+ * by tomi@esvgw.esv.co.jp
+ */
+ outb(IO_ICU1 + 1, idev->id_irq ^ 0xff);
+ #endif /* TP230 */
failures[4] = (inb(iobase + com_iir) & IIR_IMASK) - IIR_TXRDY;
if (idev->id_irq != 0)
failures[5] = isa_irq_pending(idev) ? 1 : 0;
failures[6] = (inb(iobase + com_iir) & IIR_IMASK) - IIR_NOPEND;
BTW, are you using new sio.c with our patch to use PCMCIA card? If
you're using it, above patch has been incorporated.
