Logs using a SATA PCIe card [1]. The PCIe card enumerates fine but after that I observe "ata3.00: qc timeout (cmd 0xec), ata3.00: failed to IDENTIFY (I/O error, err_mask=0x4)" Logs using a Ethenet PCIe card [2]. Again here the PCIe card enumerates fine but when I give ifconfig up, it fails. If I just revert commit , the PCIe cards starts to work fine again Logs using a SATA PCIe card [3]. Here the KINGSTON SSD gets detected fine. Logs using a Ethernet PCIe card [4]. I'm able to do ping tests now. Actually I'm not able to find any obvious problems with the patch and the irq number and the memory resource also looks fine. Any idea what could be the problem?
