I think you should do the following sequence in the probe function of your PCI<br>
driver.<br>
<br>
1. pci_enable_device(pdev);<br>
2. pci_request_regions(pdev, DRV_NAME);<br>
3. pci_set_master(pdev);<br>
......<br>
<div><div class="h5"><br></div></div></blockquote><div>Okay, I have changed my drive code to follow this sequence, but still no success. It fails with the same errors as before.<br><br># insmod ./pci_skel.ko<br>PCI driver: Init function<br>

Looks we need some pci_fixup to modify them. Firstly I think you'd better 'zero'<br>
all BARs of your PCI device on the function, pci_scan_device, on the file,<br>
drivers/pci/probe.c. On there you can dedicate that once your device is probed.<br>
Please check the each BAR's value again after the above fix.<br>
<br></blockquote><div><br>Okay, I have set the BARs with all zeros in the pci_scan_device() function. Below is the diff of the changes done by me.<br><br>--- /data/sources/linux-2.6.35/drivers/pci/probe.c 2010-08-02 03:41:14.000000000 +0530<br>
