ahcich0 issues in VB

[pluknet]

Hi.

There are two issues on RELENG_8 running in VirtualBox with ahci_load="YES".
Transcribed manually (btw, smbd knows how can I get this via clipboard?).

1. Slightly older RELENG_8 (from 27 Nov or so).
ahcich0: Timeout on slot 22
ahcich0: is 00000000 cs 003ffffc ss ffffffff rs ffffffff tfd 50 serr 00000000

while portsnap update, then most processes stuck in [getblk]
Jump to ddb manually, bt:

sched_switch
mi_switch
sleepq_switch
sleepq_wait
__lockmgr_args
getblk
breadn
bread
ffs_update
ufs_inactive
VOP_INACTIVE_APV
vinactive
vrele
fdfree
exit1
sys_exit
syscall

2. RELENG_8 csuped from yesterday: the problem appears during boot.
[...]
Waiting 5 seconds for SCSI devices to settle
em0: link state changed to UP
ahcich0: Poll error on slot 0, TFD: 0131
ROOT MOUNT ERROR:
If you have valid mount options, reboot and first try the following
from the loader prompt:
            set vfs.root.mountfrom.options=rw
[...beyond as usual when kernel can't found a boot disk..]
