Last time I upgraded it was at Aug. 25(see Environment), and it works fine. After I installed the kernel(r255183), it cannot boot and stuck at mountroot prompt. It says that "mounting from ufs:/dev/da0p2 failed with error 19". I tried typing "?" to list bootable devices, but only CD-ROM is on list, seems /dev/da0 is not recognized by the new kernel. I then booted kernel.old, and everying is OK. So it is not my hardware problem. I think the mps driver MFCed has some bug in it. If you need more details, please contact me via email. I normally reply in 24h. Thank you. >How-To-Repeat: Find a SAS2008 card, connect a harddisk to it, install the lastest version of 9-STABLE and boot. >Fix: None. >Release-Note: >Audit-Trail: >Unformatted:
