[Bug 48263] Re: Laptop freezes if the NIC (VIA VT6102 Rhine II) is 'bounced'

[Michael R. Bernstein]

** Summary changed:

- Laptop crashes if the NIC (VIA VT6102 Rhine II) is 'bounced'
+ Laptop freezes if the NIC (VIA VT6102 Rhine II) is 'bounced'

** Description changed:

  I have installed Dapper on an Averatec 3250HX-01, and the networking
  does not work (ie. nothing but the machine's own IP can even be pinged),
  despite being recognized and setup.
  
  This laptop has a Via VT6102 networking chipset (Rhine II) and a RaLink
  RT2500 wireless chipset.
  
  If I try to 'bounce' (disable and then enable) the wired (or wireless)
  ethernet using the 'Networking' program, the machine locks up.
  
  dmesg indicates there is some kind of IRQ conflict (both the wired and
  wireless chipsets are assigned to IRQ 11).
  
  Wired networking works perfectly under Breezy (I verified this by
  booting from a Breezy LiveCD) despite the same conflict. Furthermore,
  under Breezy the video chipset is *also* assigned to IRQ 11, so this may
  be a red-herring.
  
  A helpful soul on #ubuntu suggested I try adding pci=routeirq to the
  boot params, but this did nothing.
+ 
+ Please note the attachments to this bug, which now include dmesg output,
+ 'lspci -vv output', and 'cat /proc/interrupts' output, from both my
+ 3250HX-01 laptop as well as Centaur5's 3225HS-20 laptop, which has
+ identical networking chipsets and identical symptoms.
+ 
+ Also attached is some output from Breezy, which works correctly, unlike
+ Dapper.
