Hi!
030 is known to crash sometimes
The only thing we have (as far as I know) for now is my outdated "[PATCH RFC 0/5]
Fix accidental crash in iotest 30" (6 moths ago, time flies fast :\
https://patchew.org/QEMU/[email protected]/
I hope one day I'll return to this thing.. But everybody welcome to get ahead
of me :)
Note: we dropped iotest 30 from auto group in
commit e2c5093c993ef646e4e28f7aa78429853bcc06ac

iotests: 30: drop from auto group (and effectively from make check)
And original commit message (look at
<[email protected]> in list) said
So it seems reasonable to drop test from auto group at least until we
merge "block: update graph permissions update"
(and it also showed that test still crash on these series, but much less often)
Now this series is merged. And it seems to me that really, I see crashes in
iotest 30 rarely. But they still happen sometimes.

Folks,
I have CI on s390 on qemu/master for each commit. And from time to time I do
get spurious failures of 030. (always 030 and nothing else).
I have a hard time reproducing this manually so I cannot debug this at the
moment. Has anyone seen this as well?
