SRU justification: Impact: Socketcom's Socket Bluetooth card causes a kernel panic when it is plugged in, either during boot or after boot.
Unfortunately commit ac019360fe311dd6aa11b358a02eb3a61675882e treats an early interrupt during hardware and driver initialisation as a fatal driver bug and generates an oops which is rather a heavy handed way of catching this interrupt. Reverting this commit causes the driver to catch the interrupt with a kernel warning rather than a fatal oops. Testcase: Without the revert, when the Socketcom Socket Bluetooth is plugged in (during or after boot) the kernel panics. With the revert, there is no panic, instead the device causes a kernel warning about a spurious interrupt. Tested by Quinn Plattel https://bugs.launchpad.net/ubuntu/+source/linux/+bug/217659/comments/17 from a PPA build with this revert. This fix reverts commit ac019360fe311dd6aa11b358a02eb3a61675882e which introduced the oops. ** Changed in: linux (Ubuntu) Assignee: Stefan Bader (stefan-bader-canonical) => Colin King (colin-king) Status: Triaged => Fix Committed -- dtl1_cs causes kernel panic when plugged in https://bugs.launchpad.net/bugs/217659 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
