Title:
r8192se_pci: DHCP does not work when using WPA2-PSK
--
ubuntu-bugs
For me gnome-power-manager has approximately a 170KB leak every 10
minutes on Ubuntu 10.04 amd64, and indicator-applet has about a 16KB
leak every 10 minutes. Using atop and looking at the history makes it a
bit obvious. All patches applied, still broken and leaking memory. :(
This is after all
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
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

It was a problem with 2-3 consecutive reboots with 19. I believe it has

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.
Public bug reported:
It seems to always occur during an mdcheck/resync, if I am logged in via
SSH it is still somewhat responsive and basic utilities like dmesg will
work. But it apppears any write I/O will hang the terminal and nothing
is written to syslog (presumably because it is blocked).

Hi Kleber,
I installed it later yesterday, but I won't know until the next resync. This
has been a problem since at least linux 5.4 kernel that shipped with Ubuntu
20.04. I don't think I had these problems on Ubuntu 18.04 LTS, the same
hardware, running the linux-image-generic at that time.

with latest linux-image-generic and was able to reproduce it within
maybe 10 or 15 minutes. Exactly the same issue.

# assemble raid devices
