Hi all,
I was trying to "modprobe qla2300" on an ia64 with 2.6.2-rc2 kernel.
I had successfull modprobed it already with 10 FC disks out
behind a switch. I powered up another tray of disks connected
to the same FC switch which had some defective disks in it.
The error daemon oops'd on the next modprobe attempt.
I'll power off the tray tomorrow but leave it connected.
If anyone needs more info, please ask.
BTW, I'm using David Mosberger's lia64.bkbit.net/linux-ia64-2.5
source tree. I'm open to trying a different bk source tree
or patches against david's tree if something is obvious.
thanks,
grant
ps. I know about the 520-byte sector disks shown below.
I will revert those to 512 byte sectors and use them.
pps. if someone wants the previous output, it might be in /var/log
