Some times ago, I wrote that dhclient caused kernel panics with -current.
A -current kernel from Mar 9 didn't crash. Neither did previous versions.
The problem really happens as soon as something is done to the NIC.
dhclient crashes the kernel, but a simple 'ifconfig' also does. It seems
related to the NIC or to the phy. It's a Via Rhine (vr*) based NIC. On
another host with a Realtek NIC, everything goes fine.
GDB seems to confirm this :
#0 0x1000 in ?? ()
#1 0xe02834a8 in boot ()
#2 0xe0146cc2 in panic ()
#3 0xe0144d04 in pool_get ()
#4 0xe0159a5f in m_devget ()
#5 0xe02b188b in vr_rxeof ()
#6 0xe02b1cb8 in vr_intr ()
#7 0xe01015e1 in Xrecurse11 ()
if_vr.c was AltQified some days ago. I reverted the change with no
success. Same crash every time. It happens with hand-compiled kernels, but
also with the generic kernel from the latest snapshot.
Hope this helps...
