Subject: vgdisplay problem with hifn795x

Dear all,

I'm testing one hifn card with cryptsetup, but the vgdisplay will hang after I created the LV
by cryptsetup. If I reboot the system, the system will hang during activating LVs at boot time.

The system is CentOS5.2+2.6.27.4 kernel. I used all default options to create the encryption disk.

[[email protected] ~]# cryptsetup status encrypt
/dev/mapper/encrypt is active:
cipher: aes-cbc-essiv:sha256
keysize: 128 bits
device: /dev/mapper/vol-encrypt
offset: 1032 sectors
size: 2096120 sectors
mode: read/write

I searched the alias, but no clue for vgdispaly.
Could you please give some hints? (Please cc me because I'm not in this alias yet)
Thank you!

Regards,
Lingbo

I do not know what is vgdisplay, but HIFN driver got several bug fixes
recently, so if problem is related to the driver, likely it was fixed.
You may try pulling driver from the cryptodev repo [1] into your kernel
build system and compile it, or wait for the kernel update from your
vendor. Likely this bugfixes will be pushed into mainline tree in 2.6.29
merge window.
