Subject: [regression v4.11] 617f01211baf ("8139too: use napi_complete_done()")
Date: Fri, 7 Apr 2017 21:17:54 +0300 [thread overview]
Message-ID: <20170407181754.GL30290@intel.com> (raw)
Hi,
My old P3 laptop started to die on me in the middle of larger compile
jobs (using distcc) after v4.11-rc<something>. I bisected the problem
to 617f01211baf ("8139too: use napi_complete_done()").
Unfortunately I wasn't able to capture a full oops as the machine doesn't
have serial and ramoops failed me. I did get one partial oops on vgacon
which showed rtl8139_poll() being involved (EIP was around
_raw_spin_unlock_irqrestore() supposedly), so seems to agree with my
bisect result.
So maybe some kind of nasty thing going between the hard irq and
softirq? Perhaps UP related? I tried to stare at the locking around
rtl8139_poll() for a while but it looked mostly sane to me.
