Hi! I'm testing my new hard drive IBM IC35L040AVER07-0 40 Gb with 4.5-PRESELEASE copying 700M movie file from SONY CD-RW CRX140E. My motherboard is Iwill BD100Plus 440BX (ATA 33). ad2: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata1-master tagged UDMA33 acd1: CD-RW <SONY CD-RW CRX140E> at ata1-slave using UDMA33 I mount CD-RW (iso9660 filesystem) and copy file using Midnight Commander. In the middle of copying I get these messages written to console: ad2: READ command timeout tag=0 serv=0 - resetting ad2: invalidating queued requests ata1: resetting devices .. ad2: invalidating queued requests done ad2: no request for this tag=0?? ad2: invalidating queued requests ad2: READ command timeout tag=0 serv=0 - resetting ad2: invalidating queued requests ata1: resetting devices .. ad2: invalidating queued requests done ad2: no request for this tag=0?? ad2: invalidating queued requests ad2: READ command timeout tag=0 serv=0 - resetting ad2: invalidating queued requests ata1: resetting devices .. ad2: invalidating queued requests done ad2: no request for this tag=0?? ad2: invalidating queued requests ad2: READ command timeout tag=0 serv=0 - resetting ad2: invalidating queued requests ad2: trying fallback to PIO mode ata1: resetting devices .. ad2: invalidating queued requests After fallback to PIO mode system spends 88% of my Celeron-450 for iterrupts. One question: need this be fixed, and if so, how? Eugene Grosbein To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
