Re: 2.6.24-rc6 oops in net_tx_action

Kernel is 2.6.24-rc6 + linuxpps patches, which are all to the serial
port driver.

2.6.23 was known stable.  I haven't tested earlier 2.6.24 releases.
I think it happened once before; I got a black-screen lockup with
keyboard LEDs blinking, but that was with X running so I couldn't see a
console oops.  But given that I installed 2.6.24-rc6 about 24 hours ago,
that's a disturbing pattern.

It is probably this one:

Thanks!  I got the patch from
http://marc.info/?l=linux-netdev&m=119756785219214
(Which didn't make it into -rc7; please fix!)
and am recompiling now.

Actually, I grabbed the hardware mitigation followon patch while I was
at it.  I notice that the comment explaining the format of CSR11 and
what 0x80F10000 means got lost; perhaps it would be nice to resurrect it?

0x80F10000
  80000000 = Cycle size (timer control)
  78000000 = TX timer in 16 * Cycle size
  07000000 = No. pkts before Int. (0 =  interrupt per packet)
  00F00000 = Rx timer in Cycle size
  000E0000 = No. pkts before Int.
  00010000 = Continues mode (CM)
  
(Boy, that tulip driver could use a whitespace overhaul.)

Jeff is busy so he's asked me to pick up the more important
driver bug fixes that get posted.

I'll push this around, thanks.

Much obliged.  It's only 11 hours of uptime, but no problems so far,
even trying abusive things like "ping -f -l64 -s8000".
