Sym53c8xxx woes

OK, so I've upgraded our NEC AzusA 16-way to 2.4.18, and ran into a li'l problem. When I've 20GB of RAM or more enabled, the Sym53c8xxx v1 driver crases on boot. The v2 driver won't even compile.

Luckily, the SCSI drives are all on a qla1280 controller, so I can simply leave the Symbios support out, but still this is a problem.

Without the Symbios driver, I can run it with all 16 procs and 32GB ram.

ObPlug: Our 16-way is available to all and sundry, and I'm currently bringing up a couple of 4-way Lions as well. A couple 2-ways are in the pipeline.

HP ran into a similar problem and crippled the sym53c8xxx to only register for 32-bit DMA support. Things work fine that way.

Hi Aaron,

I guess the compile error would be caused due to no definition of dma64_addr_t. right?
I that case, you can make a kernel with setting "DMA addressing mode" to be 0. DMA 64bit mode for Sym53c8xx won't work on AzusA, anyway.

Regards,
Kimi
