EISA support in cpqarray broken in 2.6.x kernel

EISA support in cpqarray broken in 2.6.x kernel

[Erik van Engelen]

Hello,

The cpqarray driver lost support for the EISA bus from kernel 2.4 to 
2.6. This causes a kernel panic during boot.

It is very clear there is a problem with this driver. As i already 
described:
In the initializing of the driver (cpqarray_init) the PCI and EISA bus 
are initialized (cpqarray_pci_detect, cpqarray_eisa_detect). In 
cpqarray_eisa_detect the pci_dev is set to NULL. A few lines later (line 
397) a call to hba[i]->pci_dev->dma_mask is made. This is clearly 
impossible.

I already did all the tests discribed by the support team at HP and came 
to the conclusion it is the EISA bus that is the problem. That's why I 
asked if the support is coming back in the driver?

I send this message to the mailinglist because i think the maintainers 
don't have the answers for the problem.

Greetings.
Erik

Please try this installation with no PCI cards, using only the embeded SCSI (terminate the unused channel).  Also, please minimize the amount of memory and try to revert to a single processor.  If the installation fails, it is possible configuration, firmware or main system component issues.  If the installation works, then the problem is with one of the components removed (yes maybe the Smart Array).  At that point, I would first try adding only the Smart Array and then other components one at a time until the failure can be reproduced.  This is a long process, but afterwards it will allow greater focus on the one problem area.
