Booted to single user and was able to get some network operations going with this version (w/ previously mentioned update). However, at the step where I start CUPS, I got a number of traces on the display referring to parport_pc related function calls [but I don't use a parallel printer...]. It ended with:
NMI Watchdog detected LOCKUP on CPU1, eip c0139b22, registers: [not sure you want the all the details, I'll put a few key items in and can try to reproduce on request]
Modules linked in: parport_pc lp parport autofs4 sunrpc 8139too mii dm_mod uhci_hcd ext3 jbd CPU: 1 ... EIP is at sub_preempt_count+0x82/0xa0 ... Process ksoftirqd/1 (pid:5 ...)
Pid: 1825, comm: modprobe ... CPU: 0 ... EIP is at flush_tlb_others+0x90/0xf0
(stack trace shows sys_init_module, parport_pc_init, ... parport_announce_port, mcount, parport_pc_probe_port, parport_announce_port, __mcount, parport_daisy_init, ... parport_wait_event, down_write_interruptible, error_code, show_stack, etc.) preempt count: 00010006 ... console shuts up...
Alt-Sysrq keys are recognized (displays command) but don't display any data. Will send whatever made it into to the system log shortly.
