Hi Merlin,

Thanks for the information. I will look into it.

And can you provide us more information please?
e.g. firmware ver, output of `lspci -vvnn`, what kind of operation you use to 
reproduce this issue.

Thanks a lot.

[Bug 1935583] Re: Kernel panic on Bionic 5.4.0-47-generic

2021-07-12 Thread Ike Panhc 
There are many ways to corrupt stack or pointers to stack. Since this
issue happens in out-of-tree mlx5 modules, it looks to me that where you
shall look at.

Please let us know if you can reproduce this issue without any out-of-
tree module.

I notice there is a traceback about mlx5, however, while I check vmcore,
the STACK_END_MAGIC haven't been overridden (I mean $rd 'stack_address'
print 0x57AC6E9D) how can?


//kernel/sched/core.c
static inline void schedule_debug(struct task_struct *prev)
{
#ifdef CONFIG_SCHED_STACK_END_CHECK
if (task_stack_end_corrupted(prev))
panic("corrupted stack end detected inside scheduler\n");
#endif

The log shows that you are running non-Ubuntu mlx5 modules, and the
traceback is in those modules. Marking Invalid - you'll need to reach
out to your mlx5 driver provider for support.
