The Kernel Virtual Memory errors are at the bottom. Normally these units boot with no problems. The only thing I did different prior to reboot was sync the system time, then write to the hwclock (which has been done before without this problem). The unit then completely locked and I had to power cycle it to reboot. On the next boot everything was fine. I didn't see any JFFS2 errors on next boot either. I tried to duplicate it with the same steps, and it boots normally. Any ideas on what may have caused this? Thanks in advance, -Brian --snip-- [root@JBMgateway-v50 lib]# ntpdate 192.10.20.6 19 May 16:24:06 ntpdate[106]: step time server 192.10.20.6 offset -17863.460593 sec [root@JBMgateway-v50 lib]# date Mon May 19 16:24:08 CST 2003 [root@JBMgateway-v50 lib]# [root@JBMgateway-v50 lib]# hwclock --systohc [root@JBMgateway-v50 lib]# reboot The system is going down NOW !!
