Been digging around for a solution or confirmation of this for a while
now without much luck. Forgive me if there's a solution to this I'm just
not seeing.
Getting some ugly libata related errors in my guest like
ata2: DRQ=1 with device error, dev_stat 0x49
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 0x4a data 8
in
res 41/50:03:00:00:20/00:00:00:00:00/a0 Emask 0x3 (HSM
violation)
ata2: soft resetting port
ata2.00: configured for MWDMA2
ata2: EH complete
when running a stock install of Fedora 7 (x86_64) in qemu (the stock
fedora package of qemu 0.9.0 or kvm-33). Tried upgrading to the latest
updated kernel 2.6.22.1-33.fc7, then the latest development one with no
change.
Tracked it down to hald-addon-storage which is polling the cdrom with
SG_IO and GPCMD_GET_EVENT_STATUS_NOTIFICATION which is trying to "check
if eject button was pressed".
In my search I found a brief example program in this ticket
https://bugzilla.novell.com/show_bug.cgi?id=145147 which replicates the
issue reliably here without involving hal.
The workaround I found was to run
hal-disable-polling --device /dev/scd0
but given the lack of success I had finding other people reporting this
exact issue in libata proper, I'm guessing it might be something with
the cd-rom emulation of which fixing is way over my head :)
Guest dmesg and test case attached.
Anyone else seeing this?
