Hello managers!
my machine can't boot into multiuser mode after rebuilding kernel. It crashes
after loading driver for FORE PCA200EUX ATM card. The problem maybe isn't
related to this card. Here are few lines from syslog.

The problem appears only when I set in /etc/sysconfigtab
generic:
lockmode = 4
If I remove it, machine boots with default lockmode=0, and is fine.
Could one explain me what means each lockmode version [0 - 4]?
Lockmode=4 was recomended to me with sys_check to trace better system needs.
Also sys_check recommended to set AllowQuotaFailuresForRoot=1 in advfs: section
in sysconfigtab. However, during boot system complain that there's no such
variable. Does anyone have an explanation?
If anyone would like to tell me exactly where the problem was and how he did it,
he's more than welcome!
