I can pull video via firewire from a set top box using
test_mpeg2 for hours (97GB is my current record) if using a
UP kernel. The machine locks hard after about 500MB using an
SMP kernel. No messages, no altsysreq keys. It seems to
lock faster if I make the machine busy (disk and cpu). One

The machine is x86_64 SMP. I also got the oops in the Fedora kernels:
2.6.20-1.2933.fc6 and 2.6.20-1.3017.fc7. The system isn't locked solid but
it seems anything touching the scsi disks hangs. I also twice got this early
in the boot and it stopped booting.
Anything I can do to help just ask.

I am using raid6. Am I at risk after applying this patch?
Thanks for your time!

I seem to recall reading that after a power failure a modern IDE drive gets
enough power from the motor spinning down to always be able to write the cache
to the media.
Am I wrong about that

Here is 2.6.13-rc5-RT-V0.7.52-16 SMP with CONFIG_DEBUG_SLAB set.
How may I help?

This particular module (uhci-hcd) caused hangs with many recent up rt kernels
when loaded by rc.sysinit so I put it in the hotplug blacklist and loaded it
manually later. This time I got a BUG.

You don't want tmpfs. You want either (1) ramfs and copy the data once at

Or set your console for more than 80x25 using SVGATextMode. I use
/usr/sbin/SVGATextMo
And here's another sample output for you:
