Hi, I got regular error messages in syslog, as in: Feb 26 08:14:18 puma kernel: ata5.00: qc timeout (cmd 0xa0) Feb 26 08:14:18 puma kernel: ata5.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen Feb 26 08:14:18 puma kernel: ata5.00: irq_stat 0x40000001 Feb 26 08:14:18 puma kernel: ata5.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 Feb 26 08:14:18 puma kernel: cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Feb 26 08:14:18 puma kernel: res 51/20:03:00:00:00/00:00:00:00:00/a0 Emask 0x5 (timeout) Feb 26 08:14:18 puma kernel: ata5.00: status: { DRDY ERR } Feb 26 08:14:18 puma kernel: ata5: hard resetting link Feb 26 08:14:18 puma kernel: ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Feb 26 08:14:18 puma kernel: ata5.00: configured for UDMA/33 Feb 26 08:14:18 puma kernel: ata5: EH complete The device in question is my DVD drive: <6>ata5: SATA max UDMA/133 abar m2048@0xe0526000 port 0xe0526200 irq 218 <6>ata5: SATA link up 1.5 Gbps (SStatus 113 SControl 300) <6>ata5.00: ATAPI: Optiarc DVD-ROM DDU1671S, 1.11, max UDMA/33, ATAPI AN <6>ata5.00: applying bridge limits <6>ata5.00: configured for UDMA/33 There is no DVD inserted in the drive at the time of these messages. Do these timeout messages somehow influence the access to other SATA devices? Particularly, I have two SATA 750GB disks in this workstation, are they handled independently? I assume that the timeout messages are caused by ivman that I use for automatic mounts of DVDs and USB sticks. (I use neither GNOME nor KDE as a desktop environment.) Any recommendations for an other volume manager that does not cause such timeouts? Any hints for other root causes of the error messages, where could I look at? Or should I simply ignore the error messages? I hope that somebody has some information or ideas for me, TIA. :-) Joachim PS: This is on openSUSE 11.1 32bit, w/ all patches, in case it matters. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Joachim Schrod Email: jschrod@acm.org Roedermark, Germany -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
