Currently my desktop freezes very occassionally for a short time, and has nothing to do with insufficient system resources. Afterwards I'll see something like this in dmesg [15523.867808] ata3: EH in SWNCQ mode,QC:qc_active 0x7 sactive 0x7 [15523.867822] ata3: SWNCQ:qc_active 0x1 defer_bits 0x6 last_issue_tag 0x0 dhfis 0x1 dmafis 0x1 sdbfis 0x0 [15523.867834] ata3: ATA_REG 0x40 ERR_REG 0x0 [15523.867840] ata3: tag : dhfis dmafis sdbfis sactive [15523.867846] ata3: tag 0x0: 1 1 0 1 [15523.867868] ata3.00: exception Emask 0x0 SAct 0x7 SErr 0x0 action 0x6 frozen [15523.867876] ata3.00: failed command: WRITE FPDMA QUEUED [15523.867891] ata3.00: cmd 61/08:00:80:6b:c3/00:00:1d:00:00/40 tag 0 ncq 4096 out (before anyone asks, BZ #917826) dmesg reports things in chronological order and with a timestamp, so if there's a recent event connected to the freeze it's fairly apparent from the jump in timestamps after startup and login events. If the problem is an application hogging resources then top will help find it. If neither of these provide any useful information then /var/log/messages contains a bit more information than dmesg and can be worth checking. If none of those show anything suspicious, or at least associated in timing, then the desktop itself is the top suspect remaining. -- imalone http://ibmalone.blogspot.co.uk -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
