Public bug reported: [Impact] When using DW5823E WWAN modem (iosm kernel module) with IPSec (xfrm kernel module), the system will eventually hang after using the network.
[Fix] The upstream fix is still under review here: https://lore.kernel.org/netdev/[email protected]/ Out of the urgency, we'd apply this patch to be an Ubuntu sauce patch into Noble 6.8. [Test Plan] 1. Install the latest Ubuntu oem / public image on the system with DW5823e WWAN card 2. insert the SIM card into the GSM modem and establish a connection to the GSM network 3. setting up an IPSec tunnel (through the XFRM kernel module). 4. launching a browser, e.g. Firefox, and running any HTML page on the remote side (i.e. tunnel communication), even a 'ping' through tunnel will cause the issue [Where problems could occur] May cause regression. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Noble) Importance: Undecided Assignee: En-Wei Wu (rickywu) Status: In Progress ** Tags: oem-priority originate-from-2078430 somerville ** Also affects: linux (Ubuntu Noble) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Invalid ** Changed in: linux (Ubuntu Noble) Status: New => In Progress ** Changed in: linux (Ubuntu Noble) Assignee: (unassigned) => En-Wei Wu (rickywu) ** Tags added: oem-priority originate-from-2078430 somerville -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2085431 Title: System hang when using DW5823E WWAN on Arches 15 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2085431/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
