You have changed some on the kernel configs? On the sheduler!
Please reenable CONFIG_IOSCHED_AS and let the default sheduler as
"anticipatory". All other shedulers have not well tested. I have known
one error from other user about sheduler CFQ in combination with async
block device.

Please enable also CONFIG_PREEMPT and CONFIG_PREEMPT_BKL.

For error tracing reenable CONFIG_DEBUG_KERNEL. Then you should see the
daedlock, instead a hanging pc.

No. The debug-daemon can not help, if the guest kernel hangs. This is a
symptop of a daedlog. For example waiting for a mutex with disabled
interrupts.

What distro you runs?
What is the compiler version, you used for kernel build?
