Bug ID: 253860
Summary: ccp(4) immediately hangs when creating geli device
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
The ccp(4) driver immediately hangs if I try to use it on a freshly installed
13.3-BETA3 system. I can load the driver, but it immediately hangs the first
time I try to use it, which is by creating a geli device.
> sudo kldload ccp
> sudo mdconfig -a -t swap -s 64m
md0
> sudo geli onetime -e aes-xts -l 256 -s 4096 /dev/md0
<hangs>
In another terminal, dmesg shows that it ccp is indeed being used:
> dmesg
...
ccp0: <AMD CCP-5a> mem 0xfc000000-0xfc0fffff,0xfc1cc000-0xfc1cdfff irq 54 at
