Should not be a chipset support problem, because other disk works without a problem on this Intel Q35 chipset without any problems/timeouts. Maybe its because these non default features of ext2 enabled on the Linux side: - dir_index - large_file Regards, vermaden >How-To-Repeat: # mount -t ext2fs /dev/ada1s1 /mnt/GREEN # cd /mnt/GREEN # ls small_dir (contents ...) # ls big_dir (no output) .. and dmesg(8) shows two lines (always two lines for single ls command on big directory: g_vfs_done():ada1s1[READ(offset=-711084466176, length=4096)]error = 5 g_vfs_done():ada1s1[READ(offset=-711084466176, length=4096)]error = 5 ~ % tune2fs -l /dev/ada1s1 tune2fs 1.41.8 (11-Jul-2009) Filesystem volume name: <none> Last mounted on: <not available> Filesystem UUID: d8e5e867-db65-499b-b158-1887bf718e45 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: ext_attr resize_inode dir_index filetype sparse_super large_file Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: not clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 91578368 Block count: 366284000 Reserved block count: 0 Free blocks: 232569649 Free inodes: 91511889 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 936 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 256 Filesystem created: Fri Dec 18 19:34:50 2009 Last mount time: Sat Jan 9 15:18:02 2010 Last write time: Sat Jan 9 15:43:23 2010 Mount count: 0 Maximum mount count: 27 Last checked: Sat Jan 9 15:18:02 2010 Check interval: 15552000 (6 months) Next check after: Thu Jul 8 16:18:02 2010 Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group wheel) First inode: 11 Inode size: 128 Default directory hash: half_md4 Directory Hash Seed: e48cf467-623f-4625-99c8-19c028a27620 >Fix: >Release-Note: >Audit-Trail: >Unformatted:
