Re: 2.5.44: problemn when shutting down, drivers/base/power.c and the global_device_list

[Jurriaan <thunder7@xs4all.nl>]

I tried this patch:

and it didn't work - still hangs in 'Shutting down devices'.

But I added some debugging output:

void device_shutdown(void)
{
	struct list_head * entry;
	int i=0;
	
	printk(KERN_EMERG "Shutting down devices\n");

	down(&device_sem);
	list_for_each(entry,&global_device_list) {
		struct device * dev = to_dev(entry);
	        printk(KERN_EMERG "found device in global_device_list present %d ID '%s' name %s head %08lx entry %08lx next %08lx prev %08lx\n", 
				device_present(dev), 
		 		dev->bus_id ? dev->bus_id : "<none>",
				dev->name ? dev->name : "<none>",
				&global_device_list, entry, entry->next, entry->prev);
		if (device_present(dev) && dev->driver && dev->driver->shutdown) {
			pr_debug("shutting down %s\n",dev->name);
			dev->driver->shutdown(dev);
		}
		if (i++ == 128) goto out;
	}
out:
	up(&device_sem);
}

and I see a loop when shutting down:

ID 'scsi0'
ID '0:0:1:0:gen'
ID '0:0:1:0'
ID '0:0:2:0:gen'
ID '0:0:5:0:gen'
ID '0:0:5:0'
ID 'scsi0'

and then it goes on to 0:0:1:0:gen and repeats itself.

With the crude '>128 devices, skip the rest of it' above, it actually
shuts down. I still wonder if this warning about might-sleep in my dmesg
can have anything to do with this; it occurs just when registering the
scsi card. A full dmesg has been attached.

Kind regards,
Jurriaan
