I'm seeing some things I'm not comfortable with in the security output from one of my systems - a new Dell Dimension 8300. This is what I'm seeing: key2.keyslapper.org kernel log messages: > ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=31672255 > ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=31672383 The ad4 timeouts have happened before. They usually coincide with a moderate to large port build. If I'm building some huge package like OpenOffice or xorg when this happens, the whole system hangs. No mouse, keyboard, nothing. Last time I just left it to see if things resolved, and next morning I found it freshly rebooted. (I did eventually get both OpenOffice and xorg built though) Ad4 is a 160G hard drive with the following partitioning: $ df -k Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad4s1a 1012974 57462 874476 6% / devfs 1 1 0 100% /dev /dev/ad4s1h 57896520 4 53264796 0% /export /dev/ad4s1g 60931274 2371112 53685662 4% /home /dev/ad4s1e 1012974 7882 924056 1% /tmp /dev/ad4s1f 20308398 4000050 14683678 21% /usr /dev/ad4s1d 8122126 85068 7387288 1% /var fdisk output is: # fdisk ******* Working on device /dev/ad4 ******* parameters extracted from in-core disklabel are: cylinders=310019 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=310019 heads=16 sectors/track=63 (1008 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 312496317 (152586 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 1023/ head 254/ sector 63 The data for partition 2 is: The data for partition 3 is: The data for partition 4 is: Any other info that would help, please let me know, but I'd like to know what the cause could be and how to fix it.
