Do you have that enable, and if yes would you mind disabling it to see
if that's the culprit?
Ken,
Ok, guess something is amiss with the CD-ROM drive on this notebook,
as in GNOME, it flashes an icon of a CD on the desktop from time to
time, as if it has detected a disc in the drive. But of course there
is no disc in the drive. I believe it did the same with 6.3 though,
but as said before didn't ever panic due to this issue.
So, some anecdotal info, after running RC2 for a few days now. It
seems the pattern is that it seems to always panic a few minutes after
a first cold boot, but then seems to remain stable after the second
boot. Odd, as with 6.3 this didn't happen. So, I happened to catch a
panic while working in the syscons console after one of these cold
boots. As far as I can tell, the panic does have something to do with
the the CD-ROM drive, as right after I saw this message on the
console, it immediately paniced:
acd0: WARNING - PREVENT_ALLOW read data overrun 18>0
and then the panic is as follows:
kernel trap 12 with interrupts disabled
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x78
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc06d39b9
stack pointer = 0x28:0xca865c10
frame pointer = 0x28:0xca865c14
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 19 (swi6: task queue)
trap number = 12
panic: page fault
Uptime: 1h9m7s
Physical memory: 179MB
Dumping 43MB: 28 12
Dump complete
This is also the computer, as you may recall, that I can't ever get
kgdb(1) to open the core dump file. Note the uptime on that particular
boot was 1h because I pretty much let it sit idle after booting. So,
gdm loaded and then I switched to syscons, logged in, and then pretty
much let it idle, till it paniced.
Hope that helps,
- rory
