[Bug 410198] Re: 'modprobe aoe' on Karmic kernel oopses with AOE device from Jaunty
Ok I have attempted to fix the driver to initialise the request_queue structure correctly. I do not have a simple way to test this fix. I have built fixed kernels and pushed them to the URL below. If you could test these and let me know if they work better for you that would be helpful.

[Bug 410198] Re: 'modprobe aoe' on Karmic kernel oopses with AOE device from Jaunty
We are panicing when trying to register the block queue:
[ 2645.959090] kobject '' (880059ca22c0): tried to add an
uninitialized object, something is seriously wrong.
[ 2645.959104] Pid: 6, comm: events/0 Not tainted 2.6.31-5-generic #24-Ubuntu
[ 2645.959107] Call Trace:
[ 2645.959139] [] kobject_add+0x5f/0x70
[ 2645.959151] [] blk_register_queue+0x8b/0xf0
[ 2645.959155] [] add_disk+0x8f/0x160
[ 2645.959161] [] aoeblk_gdalloc+0x164/0x1c0 [aoe]
[...]
This implies we have not initialised the device queue object, which
is gen_disk->queue, this comes from the aoedev object:
aoeblk_gdalloc(void *vp)
{
struct aoedev *d = vp;
[...]
gd->queue = &d->blkq;
[...]
}
It seems we do not ever initialise the blkq. Looking at other drivers
this is typically allocated using blk_init_queue(), whereas in this driver
it is allocated directly in the aoedev structure and never initialised
appropriatly.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in linux which provides the kernel. For future reference you might be interested to know that a lot of applications have bug reporting functionality built in to them. This can be accessed via the Report a Problem option in the Help menu for the application with which you are having an issue. You can learn more about this feature at https://wiki.ubuntu.com/ReportingBugs. ** Package changed: ubuntu => linux (Ubuntu) -- 'modprobe aoe' on Karmic kernel oopses with AOE device from Jaunty https://bugs.launchpad.net/bugs/410198 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
