Re: Failure to access cifs mount of samba share after resume from sleep with 5.17-rc5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This still appears to be an issue in 5.17-rc8.

I would also not this issue appears when the samba server reboots. The
client has an unresponsive cifs mount instead of attempting to retry
the connection.

dmesg after resume from suspend on 5.17-rc8:
