Re: Advansys driver freezes kernel

Thanks Brad.

What would it be likely to take to fix the driver? I learned C a long time ago, but I am not an expert and I wouldn't have time to do a really major engineering project. Would it just be a question of trawling through the source code and changing little-endian things into big-endian things in some kind of fairly obvious way, or would it be much more complicated than that?

I have an Advansys ABP940-U2W scsi card I would like to use on a powermac 8600 under Linux. It works fine under MacOS.

Unfortunately, when I either load a kernel with advansys support built in, or I load an Advansys module, the kernel freezes. This only happens when the card is installed in my machine.

I have tried this with various differently compiled kernels from two different sets of kernel sources (2.4.20-8d (Yellow Dog 3.0) and 2.4.22 (from kernel.org)) but the same thing always happens.

There were some serious endianness bugs in the advansys driver, and
I'm not sure they were all fixed. As I recall, it was only tested on
one specific model rather than on all the supported cards.

Based on my back email archives, Jerry Quinn got it working on a 970UW
card back in 2000. The version of the driver he used didn't support
the U2W cards, and he apparently didn't have one to test. I do have both
a 970UW and a 940-U2W, but I'm not really in a position to move them
around to a ppc box or to fix the driver.
