Don't have a good window since when my last test was (almost a month on
the 10/24 tag) but my playground system experienced very strange
corruptions in any subvolume using lzo compression in last nights build.
I reverted back to my previous kernel and any files I hadn't written
that were showing corruption were fine again. Any files written on the
new(problematic) kernel were also fine after falling back to the
working version (so it just looks like something in the read path was
causing problems). The most noticible issues were my ~/.mozilla
profiles all getting obliterated, so it may be something particular to
the way firefox/thunderbird deal with profiles.
Looking at the .configs for the two kernels, the only differences that
seem important to me (that aren't just exposing more sub drivers) are:
+CONFIG_BLK_WBT=y
+CONFIG_BLK_WBT_SQ=y
+CONFIG_BLK_WBT_MQ=y
+CONFIG_INTEL_RDT_A=y
+CONFIG_COMPAT_32=y
+CONFIG_FS_IOMAP=y
+CONFIG_CRYPTO_ACOMP2=y
if any of those are a smoking gun.
I'll be available briefly each evening (GMT-8) to test/reproduce/etc.
Pat
