Thanks for the update, Alex. I am performing a "Reverse" bisect between v4.1-rc4 and v4.1-rc5 using the master branch in the mainline repo: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
I'll continue the bisect unless you prefer to do it. Here is the current bisect log: # good: [e26081808edadfd257c6c9d81014e3b25e9a6118] Linux 4.1-rc4 git bisect good e26081808edadfd257c6c9d81014e3b25e9a6118 # bad: [ba155e2d21f6bf05de86a78dbe5bfd8757604a65] Linux 4.1-rc5 git bisect bad ba155e2d21f6bf05de86a78dbe5bfd8757604a65 # good: [1d82b0baf9abd59ae6f53f3102f4e442043763a4] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input git bisect good 1d82b0baf9abd59ae6f53f3102f4e442043763a4 # good: [0b6280c62026168f79ff4dd1437df131bdfd24f2] Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net git bisect good 0b6280c62026168f79ff4dd1437df131bdfd24f2 # good: [b0f155ada4c819f06aa32b4c906e7e76350c7ec1] drm/exynos: dp: Lower level of EDID read success message git bisect good b0f155ada4c819f06aa32b4c906e7e76350c7ec1 # good: [7ce14f6ff26460819345fe8495cf2dd6538b7cdc] Merge branch 'for-linus-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs git bisect good 7ce14f6ff26460819345fe8495cf2dd6538b7cdc -- 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/1439780 Title: [Hyper-V] Fiber Channel critical target error Status in linux package in Ubuntu: Confirmed Bug description: System details: Linux version 3.19.0-11-generic (apw@gloin) (gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu12) ) #11~lp1423343v201503311833 SMP Tue Mar 31 17:40:01 UTC 2015 (Ubuntu 3.19.0-11.11~lp1423343v201503311833-generic 3.19.3) Ubuntu 3.19.0-11 Ubuntu Vivid 15.04 64bit custom kernel Platform: WS2012R2 Using a fiber channel disk partition ( dev/sde1 in this example) outputs the following error: [ 1307.744496] blk_update_request: critical target error, dev sde, sector 0 [ 1396.052488] blk_update_request: critical target error, dev sde, sector 0 [ 1456.216570] blk_update_request: critical target error, dev sde, sector 0 Creating a partition works, reading too, but first time writing it hangs for around 20 seconds and after a couple more writes the partition goes into read-only mode: #echo "test1" > test1.txt *hangs for 30 seconds* blk_update_request: critical target error, dev sde, sector 0 # echo "test2" > test2.txt blk_update_request: critical target error, dev sde, sector 289671192 Aborting journal on device sde1-8.
