Subject: qla2xxx hba crashes with older 2310 cards
Date: Friday, April 20, 2007 - 11:40 am

Hi,


I've seen some chatter about the qla2xxx driver but not paid attention, so

I'm sorry if this is a known issue.  I've got an older qlogic hba, and recent

drivers don't seem to play nice with it.  I've got the latest firmware from

qlogic's web site.  I'm using a 2.6.21-rc6 kernel from Steve Whitehouse's

-nmw git tree.  Reverting to an older driver (but same kernel) and it works.

The current driver gives this:


Starting udev: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000

 printing eip:

*pde = 1e511067

*pte = 00000000

Yes, known problem, I'm sorry these guys broke the driver for

you as well, please see this thread:

This was really a stupid change to make.

OK,OK, we heard you the first time ... the maintainers will try to fix

this in a manner acceptable to all concerned ... could we try to cool

down the public traductions now?
