Re: kernel 2.6.10: promise sx6000 not detected by i2o_block

[Juergen Krause]

Hi Alan,

thx for the quick responce.

I added the the PCI indentifier to drivers/message/i2o/pci.c as follows:

--- linux-2.6.10/drivers/message/i2o/pci.c      2004-12-26 23:38:13.801878056 +0100
+++ linux-2.6.10-test/drivers/message/i2o/pci.c 2004-12-27 00:02:25.589172840 +0100
@@ -49,6 +49,7 @@
 static struct pci_device_id __devinitdata i2o_pci_ids[] = {
        {PCI_DEVICE_CLASS(PCI_CLASS_INTELLIGENT_I2O << 8, 0xffff00)},
        {PCI_DEVICE(PCI_VENDOR_ID_DPT, 0xa511)},
+       {PCI_DEVICE(PCI_VENDOR_ID_INTEL, 0x1962)},
        {0}
 };

but now i get a kernel panic when I load the module i2o_core :-(

Any ideas what I should test now or do you need more infos?
Just let me know.
