[Qemu-devel] Qemu crashed with lsi booting

[Frediano Ziglio]

I always get an assert launching this command

sudo ./x86_64-softmmu/qemu-system-x86_64 -m 1024 -hda test.qcow
-device lsi -drive file=/dev/sdb,if=none,id=XXX -device
scsi-block,drive=XXX -enable-kvm -bios ~/seabios/out/bios.bin -serial
file:out.txt
lsi_scsi: error: Multiple IO pending for request 0x7fd1075bf100
qemu-system-x86_64: /home/fredianoz/qemu/hw/lsi53c895a.c:774:
lsi_do_command: Assertion `s->current == ((void *)0)' failed.

(sometimes I don't get the "Multiple IO ending" line).

I'm using a recent SeaBIOS which support booting from LSI SCSI.

Qemu version

$ git branch -v
* master 61dc008 Revert "audio: Make PC speaker audio card available by default"

I'm using SeaBIOS commit 9d6bac1d32b72cdf7c0ad009c1371a2e69084de3
(some minor changes in order to support 4k sectors).

Adding some debugging to SeaBIOS lsi code seems that drivers send
initial INQUIRY request but after that all requests have some problems
and lead to a lot of reset command.
