Hi, I posted on this before, and no one responded, so I went on with my way, not being able to upgrade the kernel. see earlier post: disc i/o problem trying to upgrade to latest kernel (2.6.6-1.435smp) System: Dell 2450, dual P3 866, 1GB RAM, PERC 3/Si RAID, OS on a 2-disk hardware mirror Now I've been running FC2 for about a week, and yesterday I ran into the same problem with one of my machines, with the 427 kernel. I logged into the machine, did a dmesg, and got a bunch of these: EXT3-fs error (device sda2) in start_transaction: Journal has aborted Some googling turned up this post from June 3rd: Filesystem corruption, data loss on usb drives, and more problems with FC2 and also this post from the kernel mailing list: 2.6.5-mm5-1 ACCRAID dies under heavy io load I have seen this problem when trying to upgrade the kernel rpm on 3 different 2450's! any ideas? thx, -ray
