Subject: v4.13 on nokia n900: oops during tethering
Date: Mon, 12 Feb 2018 21:10:00 +0100 [thread overview]

Hi!
During tethering, I got oops in ssi_stop_tx(), followed by failure of
GPRS. I used GPRS tethering a lot with some older kernel, and it was
stable for hours.
It seems v4.12 has the same problem. In v4.15 usb networking does not
work at all, so I can't test... v4.10 seems to have similar problem. (Testing is
slighlty tricky, as my internet connection is ... tethering using
N900.)
Any ideas?
Pavel

Subject: v4.13 on nokia n900: oops during tethering
Date: Mon, 12 Feb 2018 21:10:00 +0100 [thread overview]
Message-ID: <20180212201000.GA25608@amd> (raw)
Hi!
During tethering, I got oops in ssi_stop_tx(), followed by failure of
GPRS. I used GPRS tethering a lot with some older kernel, and it was
stable for hours.
It seems v4.12 has the same problem. In v4.15 usb networking does not
work at all, so I can't test... v4.10 seems to have similar problem. (Testing is
slighlty tricky, as my internet connection is ... tethering using
N900.)
Any ideas?
Pavel
