G'luck, Peter -- Thit sentence is not self-referential because "thit" is not a word. here is the kernel config file and kernel panic message (can't provide backtrace for this computer) : handle_workitem_freeblock: block count dev = #ad/0x20005, block = 128, fs = /tmp panic: ffs_blkfree: freeing free block State Changed From-To: open->feedback Does this problem still occur on more recent releases of FreeBSD? State Changed From-To: feedback->closed Mail to submitter bounces and essentially content-free PR. |
Doing tar -zxf about_5MB_file.tgz; rm -rf all_extracted cause kernel panic on a tunefs -n enable file system (tmp in this case). Some times even tar -xzf file cause this panic. Here are the setting on /tmp: tunefs -p /tmp tunefs: soft updates: (-n) enabled tunefs: maximum contiguous block count: (-a) 15 tunefs: rotational delay between contiguous blocks: (-d) 0 ms tunefs: maximum blocks per file in a cylinder group: (-e) 2048 tunefs: minimum percentage of free space: (-m) 8% tunefs: optimization preference: (-o) time Fix: I'm too far away from FS :) How-To-Repeat: tar -zxf about_5MB_file.tgz; rm -rf all_extracted (about 3-5 times)
