Subject: Error in syslog on 2.6.20

Message-ID: <> (raw)

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.

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
