FreeBSD 9 BETA-3 with EMC CLARiiON CX3-40 via iSCSI

[Pavel Timofeev]

Hi. I'm currently testing FreeBSD 9 BETA-3 amd64 with EMC CLARiiON CX3-40
via iSCSI.
It works very bad. Often I got 'panic:ffs_alloccg: map corrupted' and system
crashes.

I constantly get errors in FS.
For example, 8Gb part shared from cx3-40:
# iscontrol -n cx3-40
# gpart create -s GPT /dev/da1
# gpart add -t freebsd-ufs /dev/da1
# newfs -U /dev/da1p1
# fsck_ufs /dev/da1p1
And fsck find errors in clear just created FS!
It doesn't depend on partitioning (GTP, MBR, raw).

If I run something like:
# mount /dev/da1p1 /mnt
# cp -r /usr/src /mnt
I get 'panic:ffs_alloccg: map corrupted'

I don't know is it bug with iscsi_initiator, iface driver or in UFS.
Any ideas?
