[Bug 1942935] Re: kernel io hangs during mdcheck/resync
The patch hasn't made it into mainline from what I have seen, it looks like it died back in March waiting for feedback from additional kernel developers. From what I have gathered this is a deadlock scenario directly caused by pausing the resync while the system is under heavy write activity. Donald Buczek provided a reproducer which is a shell script that generates a lot of write activity and pauses/resumes the raid scrubbing. And he also provided a workaround to get the stuck system running without reboot: echo active > /sys/block/md1/md/array_state I haven't tried the patch or any of this, I pretty much eliminated the trigger which is mdcheck_start & mdcheck_continue and went back to the 18.04 LTS way of scrubbing arrays (which is basically don't pause/interrupt it once it starts). I ran through a checkarray yesterday to 100%, no problems. Meanwhile since upgrading to 20.04 LTS it has hung almost every single time through 5.4, 5.8, and 5.11 kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942935 Title: kernel io hangs during mdcheck/resync To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.11/+bug/1942935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1310350] Re: Oops __rpc_clnt_handle_event+0x48/0xd0
It was a problem with 2-3 consecutive reboots with 19. I believe it has
to do with mounting rpc_pipefs, and the stack trace also seems to align
with this, it looks like some piece of the memory structure is
uninitialized. I personally didn't notice anything between 18 and 19
that would have caused this, but I am far from a kernel expert.
It may still be present in -20, but generally I do not reboot that
frequently. I often tend to skip over several updates at a time before
rebooting.

Attached is a pcap (br0.pcap) from my wireless routers bridge interface. The wireless router is clearly sending the DHCPOFFER's, but the client is dropping them before dhclient or wireshark can see them. In any case from 58.697458 seconds to 101.878812 seconds is when I try to use NetworkManager with WPA2-PSK + DHCP. 159.123577 and on is where I have a manual wpa_supplicant.conf and a static IP, which uses WPA2-PSK and works fine. I have other devices connected to the wireless router and they all work fine. Ubuntu also works fine if I use WEP or WPA-PSK. Anything before 39 seconds is when the machine was already established with a static IP and I rebooted it. ** Attachment added: br0.pcap https://bugs.launchpad.net/ubuntu/+source/linux/+bug/701287/+attachment/1801199/+files/br0.pcap -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/701287 Title: r8192se_pci: DHCP does not work when using WPA2-PSK -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 701287] [NEW] r8192se_pci: DHCP does not work when using WPA2-PSK
Public bug reported: RTL8191SE-VA2 PCIe card does not work when using WPA2-PSK. This is a non-upstream module that Ubuntu added. I have tried updated drivers from Realtek (2.6.0019.1207.2010) and they also do not work. The card will associate with the access point if I use WPA-PSK (TKIP), but if I use WPA2-PSK (AES) it will associate and wpa_supplicant is successful but when the DHCP client is ran by NetworkManager it never sees a response to the DHCP requests. The earlier drivers supplied with Ubuntu tend to hang the OS, so I have been using the later drivers which seem *slightly* more stable.
