possible bug in __wait_on_buffer

["Callebaut, Benoît"]

Hi,

I use cramfs to load the root of my system (MPC8245 based), All is good
excepted that the kernel crash on the line
run_task_queue(&tq_disk);
I checked if this queue(tq_disk) was used elsewhere( ie something put a task
in queue) but found only a raid5 driver using it.
So I disabled it. After that I received a decrementer interrupt on place.
A workaround consisting of a loop like this :
long j = jiffies+ 2* HZ;
while (jiffies < j ) schedule();
doesn't work.
Does someone encountered the same problem or is there a bug in another part
of the code ?

Regards,
