Pretty sure cause the new kernel was the only difference
between plain 5.0 CD installation and the reboot.
If I went back and boot kernel.old it again worked ok.
Also tried HEAD with same symptoms: GENERIC is ok,
SMP gives watchdog timeouts.
Perhaps it is also dependend on the card used ?
xl0@pci0:15:0: class=0x020000 card=0x100010b7 chip=0x920010b7 rev=0x74 hdr=0x00
vendor = '3COM Corp, Networking Division'
device = '3C905C-TX Fast EtherLink for PC Management NIC'
class = network
subclass = ethernet
Also checked IRQs: no sharing from what I could see.
Any more ideas / ways how to debug this / patches to try ?
