For you information if you have not seen this.  Looks like kernel
2.6.29(-r4) has problems on SB2000 at least with the disk firmware.

I just did a scan over the driver changes for qla2xxx from 2.6.28 and 2.6.29 and they were very extensive and complicated. What we need to do to narrow this down is do a GIT bisect. I hope that you have a GIT tree handy and can do this? Luckily it's pretty easy to only bisect through the qla2xxx changes. Once you have a tree checked out, start like this: bash$ git bisect start v2.6.29 v2.6.28 -- drivers/scsi/qla2xxx/ Configure and build that kernel, see if it shows the bug. If the bug is there go into the GIT tree and say: bash$ git bisect bad else if the bug is not there say: bash$ git bisect good Rebuild and retest. Repeat this process of testing and then running "git bisect good" or "git bisect bad" until the guilty changeset is found. At most you'll need to do this 6 times. Post the result here. We'll find a way to fix this, thanks! -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@×××××××××××.org More majordomo info at -- Ferris McCormick (P44646, MI) <fmccor@g.o> Developer, Gentoo Linux (Sparc, Userrel, Trustees)
