Memory corruption ?
Looks like access after free or variable on old stack, but I cannot find
anything like this in the code.
PC is at task_blocks_on_rt_mutex+0xb8/0x2a8
Can you decode the exact code line, so we know what it tries to access ?
It crashes in different places, I think, it is in rt_mutex_top_waiter()
line 440, in plist_first_entry(), that's where offset 44 comes from, I
think. Sometimes it also crashes on BUG_ON(w->lock != lock); below that
call.
(yes, tainted, you know, it's the software that has been written before
Linux...)
Sigh....
Sorry.
Thanks
