Subject: the commit c434e5e48dc4 (rsi: Use resume_noirq for SDIO) introduced driver crash in the 4.15 kernel
Date: Wed, 18 Aug 2021 12:06:15 +0800 [thread overview]
Message-ID: <2b77868b-c1e6-9f30-9640-5c82a82f5b31@canonical.com> (raw)
Hi Marex,
We backported this patch to ubuntu 4.15.0-generic kernel, and found this
patch introduced the rsi driver crashing when running system resume on
the Dell 300x IoT platform (100% rate). Below is the log, After seeing
this log, the rsi wifi can't work anymore, need to run 'rmmod
rsi_sdio;modprobe rsi_sdio" to make it work again.
So do you know what is missing apart from this patch or this patch is
not suitable for 4.15 kernel at all?
Thanks,
Hui.
