I'm not on either list, keep me in CC. I noticed the following error on a cdrom device: ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata2.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0 res 40/00:03:00:00:00/00:00:00:00:00/a0 Emask 0x4 (timeout) ata2: soft resetting port ata2.00: configured for MWDMA2 ata2: EH complete This is the device when it was found: libata version 2.00 loaded. ata_piix 0000:00:1f.1: version 2.00ac7 ata1: PATA max UDMA/100 cmd 0x1F0 ctl 0x3F6 bmdma 0xFFA0 irq 14 ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0xFFA8 irq 15 scsi0 : ata_piix ata1.00: ATA-4, max UDMA/66, 16514064 sectors: LBA ata1.00: ata1: dev 0 multi count 8 ata1.00: configured for UDMA/66 scsi1 : ata_piix ata2.00: ATAPI, max MWDMA2 ata2.00: configured for MWDMA2 scsi 0:0:0:0: Direct-Access ATA WDC WD84AA 05.0 PQ: 0 ANSI: 5 scsi 1:0:0:0: CD-ROM LITEON CD-ROM LTN486S YQSM PQ: 0 ANSI: 5 I have a program that does a scsi TEST UNIT READY on many devices once every .1 second. The problem occured when I ejected the cdrom and closed the tray again with valid media in the drive. My program noticed media removed and inserted, then said the device was dead/unpollable. This is when I saw this error. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
