| Anyone have any luck with this or similar controllers? I've tried a number of 2.6 kernels which invariably result in a slew of i2o error messages followed by a kernel panic. |

I do have the same problem(s) with the SX6000 controller and the 2.6 kernel.
I updated the controller firmware to the lastest version (1.20.0.27) . Next I tried the gentoo-dev-sources (2.6.10-gentoo-r6) kernel and enabled the following kernel options CONFIG_I2O, CONFIG_I2O_CONFIG, CONFIG_I2O_BLOCK, CONFIG_I2O_PROC (also CONFIG_BLK_DEV_SD). Unfortunately the controller is not be recognized by the i2o_pci driver.
A description of the same behaviour can be found in the LKML: http://lkml.org/lkml/2004/12/25/86
Then Alan Cox recommends ( http://lkml.org/lkml/2004/12/26/88 ) adding the PCI identifier to i2o_pci driver. However changing the part in driver/message/i2o/pci.c to
| Code: |
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}
};

did not help. The card was now detected by the i2o_pci driver but later then the card was actiaved the kernel trapped. Turning off kernel preemption did not help either.

The same behaviour is also mentioned by another user in the LKML ( http://lkml.org/lkml/2004/12/26/138 ).
It's a sad story but AFAIK Promise does not provide drivers other than for the 2.4 kernel. |
