I installed the 16.04 HWE option on the problematic HP 6710b, but it has had no effect on the wifi. It did cause a black-screen problem and drm_wait messages, worked around by disabling SVIDEO in grub.
$ uname -rsvp Linux 4.8.0-58-generic #63~16.04.1-Ubuntu SMP Mon Jun 26 18:08:51 UTC 2017 x86_64 $ dmesg | grep firm [ 3.764045] tg3 0000:18:00.0: VPD access failed. This is likely a firmware bug on this device. Contact the card vendor for a firmware update but I have found nothing that looks hopeful. The change of wording from 'vpd r/w' to 'VPD access' follows kernel patch 8385431. I found an HP advisory about the tg3 driver for Proliant servers and a specific el6 kernel, but it doesn't seem applicable here. so still no iwl3945 firmware load. I've tried sudo modprobe -v iwl3945 fw_restart=1, with no apparent effect. -- 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/1627828 Title: iwl3945 crashes randomly Status in linux package in Ubuntu: Confirmed Bug description: Out of nothing a once properly working 0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) started to crash with: Sep 22 14:38:16 seba-Latitude-D630 kernel: [26707.320032] iwl3945 0000:0c:00.0: Error sending C_POWER_TBL: time out after 500ms.
