One thing I noticed is that even though the board supports UEFI,
there was no UEFI update procedure for it, and I had to flash via
a USB stick with a FreeDOS boot image.

I think I have narrowed the problem down to this line of code:

Are kernel modules pessimized in any way with respect to using
mutexes as compared to statically compiled kernel code?
I seem to remember some discussion a year or more ago indicating that
they would be, but I'm not seeing it in the code.
Thanks,

Yes, the mbuf allocator must occasio
Hi,
I've got an Intel D845EBG2. I have 2 ACPI related problems I'm
looking for advice on:
- ATI Rage 128 Pro TF
If I suspend to S3 from text mode on console, the screen remains blank
after resume. The system is otherwise functional, and can be logged
into remotely.
If I start X after resume,
This was on an x86, 5.0-current as of roughly 8am EST today.
Machine panic'ed when it finished /usr and moved on to /var on
a manually invoked fsck -B (I'd hit ^C to abort multi-user startup
during fsck and was surprised to see the system continue on.. ;)

panic: ffs_blkfree: freeing free
Ugh. Since it may call kmem_malloc(), UMA must hold Giant.
This is the same problem the mbuf system has, and its what's
keeping network device drivers under Giant in 5.0.
Both subsytems should probably have GIANT_REQUIRED at all entry
points so as to catch locking problems like this earlier.

I just upgraded my UP1000 from 4.7-stable to 5.0.
Only weird thing left is the console seems to drop a lot of characters
just after syscons takes over.
I see this on console:
<...>
ppc0: interrupting at ISA irq 7
sc0: on isa0
sc0: VGA <16 virtual consoles, flags=0x0>
net.inet.udp.blackhole: 0

Hi,
I've been hacking on DMA windows on alpha. While I've been getting
things wrong, I've been provoking a panic in the ata driver because
it cannot do DMA when attaching a disk.
The panic is triggered at the end of ad_attach() by the raid probe
causing a transfer to fail and the disk to be det
