Hi all,
Lenovo X300, snapshot for i386, from 20080717 (also 20080716) dumps
into dbb on boot on uvideo:
uvm_fault(0xd0814b20, 0x0, 0, 1) -> e
kernel: page fault trap, code=0
Stopped at uvideo_vs_negotiation+0x81: mov1 0x15(%eax),%eax
ddb{0}>
//no console to capture output, made some photos//
last line of output from trace:
Bad frame pointer: 0xd09555e78
Previous snapshot of a week ago was booting just fine, I sent in the
dmesg to [EMAIL PROTECTED] few days back.
snippet from previous dmesg:
uvideo0 at uhub6 port 1 configuration 1 interface 0 "Chicony
Electronics Co., Ltd. product 0x4807" rev 2.00/31.25 addr 2
video0 at uvideo0
Disabling uvideo* on ukc allows kernel to boot.
(the machine has 4G of ram, sounds like a problem already reported)
Should I file a bug for this one?
Any cluesticks/patches to try are appreciated. I can send the pictures
of trace/ps if contacted off-list.

Recently I've got several reports from users showing an uvm_fault crash in
uvideo_vs_negotiation()
and
uvideo_vs_parse_desc_frame_uncompressed()
Since I can't reproduce this crash here with my two cams at all, I would
be glad if somebody could give me temporary access to such a machine, so
we can fix this bug and move on.
If you can do that please drop me a private mail.
Thanks,
Marcus
