Hi all. I just experienced a kernel panic while copying a ~22GB file from my local drive to my NAS mounted via CIFS/SMB. Unfortunately this panic seems to have resulted in some sort of corruption, and my system is no longer booting. Please let me know what other information I can provide to help out here, and I'll provide it as soon as I can get my system working again.
