This one system that consistently has a kernel panic when running this command on an arcmsr (ARECA) device: mke2fs -F -j -J size=400 -O dir_index,filetype,resize_inode,sparse_super -i32768 -m1 -L ${HOSTNAME}.0 /dev/sda4 I have 15 other systems with identical software (all installed with the same binary gentoo packages), hardware, firmware on the RAID card, and BIOS versions on the motherboard. I have about a dozen other systems with the same model of RAID card (1280ML) and none of them have experience this issue. I suspect that this is a hardware problem with either the RAID card of the motherboard but I am reporting it because of the NULL pointer dereference. The Areca cards are all running the latest firmware (v1.44) and the motherboards are Tyan S2912s running BIOS v3.03.

Does this occur on more recent kernel versions?
we have seen softlockup problems when running fsck as recently as 2.6.27-rc5 but that is probably a separate issue from this one. I think we should close the bug out unless someone else has hit this.
Closing this, Joshua if you are having issues with later kernels, please open a new bug.
