I had been to the kernel.org and cant find the kernel 2.6.21 , the kernels available are 2.6.27.49 and above . -- Regards Agnello D'souza ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] kernel panic not syncing fatal exception due to reiserfs -- rebooted properly on ext3
Hi we had one of our mail servers , going on kernel panic mode ( not syncing fatal exception) ... cause /var/queue/postfix was on reiserfs part .. it has not been giving us any isssue quite some time , but yesterday and today it went on Kernel panic mode , when we hashed out the reiserfs part it booted properly .. we formated the part^ on ext3 later and things working fine now . Could any one have a idea why this could have happened .
