Subject: [Qemu-devel] IDE TRIM bug on at least PPC target
Date: Sat, 18 May 2013 17:30:03 +0400	[thread overview]
Message-ID: <5197825B.6050008@msgid.tls.msk.ru> (raw)

As mentioned in LP:1179104 ( https://bugs.launchpad.net/qemu/+bug/1179104 ),
there's a segfault bug in qemu process once guest tries to use some TRIM
command against an IDE device on PPC.  This makes qemu-system-ppc basically
unusable with any modern distribution, since mke2fs now issues TRIM commands
during install by default.  I think it is critical enough bug to warrant
some last-minute hunting/fixing, and it'd be a shame to make a release
of qemu with this bug.

That's more or less a JFYI for now, but I don't really know what other info
is needed, -- I already provided some structures content from a gdb session.

Thanks,

/mjt
