An "endless loop kernel output" on boot always solved with clearing logs with MegaCli -AdpEventLog -GetEventLogInfo -aAll. As for BBULearn issue, I just tested it again on one of my boxes: # ./MegaCli -AdpBbuCmd -BbuLearn -aall Adapter 0: BBU Learn Succeeded. Exit Code: 0x00 So it seems to work. I see no problems. mfi0: 3748 (312279437s/0x0008/info) - Battery relearn started mfi0: 3749 (312279437s/0x0008/WARN) - BBU disabled; changing WB virtual disks to WT mfi0: 3750 (312279437s/0x0001/info) - Policy change on VD 00/0 to [ID=00,dcp=6d,ccp=6c,ap=0,dc=0,dbgi=0] from [ID=00,dcp=6d,ccp=6d,ap=0,dc=0,dbgi=0] mfi0: 3751 (312279442s/0x0008/info) - Battery is discharging mfi0: 3752 (312279442s/0x0008/info) - Battery relearn in progress > > On Oct 22, 2009, at 8:30 AM, pluknet wrote: > >> 2009/10/15 John Baldwin <j...@freebsd.org>: >>> >>> On Thursday 15 October 2009 5:51:19 am pluknet wrote: >>>> >>>> Hi. >>>> >>>> This is 7.2-R.
