QLogicFC problems with 2.4.x?

Hi,

I was just lent a QLogic ISP2200 FC adapter and have been having a
bear of a time trying to get it to work on my Alpha ES40 and GS80. I've tried both the qlogicfc (with standard kernel) and qla2x00 (from QLogic and Compaq) driver both built-in and as modules but neither of them are working. Has anyone had success with later (I'm using 2.4.0-test11) 2.4 kernels and the QLogic FC adapter? I'm currently plugged into a Brocade switch (Plaides I, I believe) which is also attached to two pair of HSG80 FC RAID controllers. AFAIK, the 2200 is supposed to work with an FC fabric, so this should work, right? Can anyone offer any assistance? Thanks!

The driver loads for me on 2.4 on Intel, but I don't have access to an Alpha right now. Have you tried Mathew Jacob's driver? It looks like it supports Alpha.

It does, but 2.4 alpha hasn't quite worked for me (the latest matrix of support for LINUX is below- and I haven't passed Michael Declerck's testing yet). I'll be checking the latest alpha bits this week some time and I still also need to finish the kernel thread work that will allow loop events to be down OOB.

Linux Notes

2.0/2.1/2.3 support dropped. 2.0 support will be added back later, but basically, it'll be 2.0/2.2/2.4 only support.

NOTE: SOME CHANGES ARE NOW REQUIRED IN A DEFAULT KERNEL BECAUSE WE NEED
NOTE: SOME EXTRA SYMBOLS EXPORTED. SEE LINUX_BUILD INSTRUCTIONS.
NOTE: AT THIS TIME YOU MUST BOOT 2.4/i386 WITH nmi_watchdog=0
NOTE: APPENDED TO THE BOOT COMMAND LINE.

NOTE: TARGET MODE IS BROKEN IN LINUX RIGHT NOW

This release has been tested agains:

	Alpha		2.2.17		[1]
	IA-32		2.2.17		2.4.0-test11
	PowerPC		2.2.17		[2]
	Sparc64		2.2.17		2.4.0-test11

There are now patches agains 2.2.17 and 2.4.0-test11 in the linux subdirectory. Or you can build as a module in place in the linux directory. See LINUX_BUILD_INSTRUCTIONS.

[1] 2.4.0-test11 panic'd and crashed and burned in readw for me. I think that this is a known alpha arch problem at this time, so I'm going to wait until 'they' fix it.
[2] I can't find a complable 2.4 for PPC at the time of test1.

This is just to let everyone know that, thanks to Craig Ruff, I now have qlogicfc working under 2.4.11 on my ES40 and GS80. The secret is to set CONNECTION_PREFERENCE to P2P_ONLY instead of LOOP_ONLY, and to build it in to the kernel instead of as a module. My problem now is that the GS80 oopses when I try to mke2fs the second stripe set on the HSG80. This _only_ happens on the second mke2fs, not the first. Screen dump is as follows:

#mke2fs /dev/sde2

I've inlined the ksymoops output below. I still haven't gotten the qla2x00 driver working... kinda strange... I'll also be trying Matthew Jacob's driver as soon as I get the chance. Thanks for all the suggestions everyone!
