| |
Hi,
I am currently trying to debug a timer issue on v6.9-rc1 and was able to write a small reproducer module [0]. If this module gets loaded I run into a soft lockup e.g. [1]. As far I see several concurrent timers are getting soft lockups.
As far as I know, I am not doing anything wrong in my timer module [2]. Please somebody correct me if I am wrong. It does not do much, except hammering timers. I tried a longterm kernel v6.6.23 and still have issues.
I appreciate any help somebody can provide.
Thanks.
