The process doing i/o is blocked on physst at an uninteruptable priority. For example, I use the Amanda amlabel command to label a new tape and got the following: ast0: WEOF command timeout - resetting ata1: resetting devices .. device dissapeared! 3 done ata1-slave: timeout waiting to give command=a0 s=d0 e=00 ast0: failure to send ATAPI packet command ast0: WEOF command timeout - resetting ata1-slave: timeout waiting to give command=a0 s=d0 e=00 ast0: failure to send ATAPI packet command ast0: WEOF command timeout - resetting ata1-slave: timeout waiting to give command=a0 s=d0 e=00 ast0: failure to send ATAPI packet command ast0: WEOF command timeout - resetting ata1-slave: timeout waiting to give command=a0 s=d0 e=00 ast0: failure to send ATAPI packet command ast0: TEST_UNIT_READY command timeout - resetting ata1-slave: timeout waiting to give command=a0 s=d0 e=00 ast0: failure to send ATAPI packet command ebb# ps alx|grep amlabel 1000 4037 4036 0 -6 0 1524 1044 physst DL+ v0 0:10.08 amlabel Dail This may be crappy hardware but the system shouldn't get wedged like this. >How-To-Repeat: One case was when I ran the Amanda tapetype program that deduces the amount of data that'll fit on a tape by writing 32k records until it gets an error. On hitting the end of tape the system wedged with the same kernel printfs as shown above. The second case was running amlabel as described above. >Fix: Haven't had a chance but submitting this in case there's a known fix or workaround (haven't looked in the code to see if perhaps there's a quirk table that needs tweaking). >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
