Corruption no longer visible with 4.4.0-49-generic: https://pastebin.canonical.com/171039/ Testing with Yakkety proper would be messy - what's the timeline for getting an updated 4.8 kernel into Xenial? I currently only see 4.8.0-27.29~16.04.1. ** Tags removed: verification-needed-xenial **

James, thanks for clarifying that. In that case, all my references to "hio driver 2.1.0.26" should actually say "the patch set James is testing", and the two fixes should still likely both be applied to the Ubuntu hio driver. -- You received this bug notification because you are a member of

Ming Lei comment #2 says you're the author of this patch to the hio driver: +#if (LINUX_VERSION_CODE >= KERNEL_VERSION(4,3,0)) + blk_queue_split(q, , q->bio_split); +#endif + Can you provide us with a short explanation for the git log, and also your Signed-off-by line for that patch? --

[Kernel-packages] [Bug 1638700] Re: hio: SSD data corruption under stress test

Side-note about bug in hio driver 2.1.0.26 (#1: bio_endio() shim macro sets bi_error field). This turns out NOT the cause of this data corruption bug per James' testing, but should be corrected (both in the upstream driver and Ubuntu). The idea behind this change is correct (the macro shim

[Kernel-packages] [Bug 1638700] Re: hio: SSD data corruption under stress test

Sorry - for the avoidance of doubt, neither of these changes are in 2.1.0.26 - 2.1.0.26 doesn't even include your patches. I was testing 2.1.0.26 + our patches + the 2 changes you mention. #1 does come from Huawei, #2 comes from Ming Lei of Canonical. -- You received this bug notification

(Also 2.1.0.26 is not public yet for reasons Huawei are trying to figure out, 2.1.0.25 is the last publicly available driver.) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1638700

Huawei's upstream hio driver version 2.1.0.26 introduces two changes relative to the current Ubuntu version: #1. bio_endio() shim macro sets bi_error field {{ but note bug in implementation! }} #2. blk_queue_split() call inserted ssd_make_request() James' initial test results indicate that #2
