Attention owners of dv5's and other affected models: Tired of owning a gorgeous laptop that won't wake up? Here's what YOU can do ...
I propose we make a group effort to get HP to fix this! If you have been following the discussions on the Linux Kernel bug report you'll notice the prevailing view is that this is most likely a HP BIOS bug. In this post alone we have seen other HP models cured of this same problem through a HP BIOS update. To date this has not been the case for the dv5 and other affected models. I know HP doesn't officially support Linux on this model HOWEVER a faulty BIOS is just that, a faulty BIOS, and it should be fixed regardless of whether it affects the supported OS or not. If you can prove to HP that this particular piece of firmware is flawed and that there is a good number of effected customers then maybe ... just maybe ... someone at HP will do the right thing. After all, we can only live in hope! I propose we make a group effort to contact HP support in a respectful but persistent manner so that our request might be heard by someone in their firmware coding department and tended to. Here is the worldwide HP support directory: http://welcome.hp.com/country/us/en/wwcontact_us.html Here is a suggested message to send to support (if you have a more persuasive version please contribute!): *** Dear HP Support Person, I am the owner of a HP dv5 laptop and I have learned that my firmware has a bug which is causing me some big problems. My laptop will suspend, but when it wakes up the hard drive will not reactivate so I need to reboot. You can imagine how much of a pain this is on laptop! I prefer to use a version of Linux on my laptop, and I understand that you don't support Linux, but I have discovered that there are many other people in my position and through a careful community effort we have been able to determine that a bug in the HP firmware is most likely to blame. Unfortunately the HP firmware isn't open source like our operating system so we can't fix it ourselves, and I know that you aren't obliged to help with Linux, but here's what you can do; please pass on this information to your BIOS firmware team so that they can assess our claims for themselves. If I am wrong, so be it, you won't hear from me again about this. So that you can see how we've how been able to determine this, please have a look at the following links: The Linux Kernel bug report: http://bugzilla.kernel.org/show_bug.cgi?id=12276 The Ubuntu bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/301353 (as you can see there's a lot of us) The ATA driver: http://ata.wiki.kernel.org/index.php/Known_issues (they are now recommend that user not buy HP laptops) The dv7 was cured of this very same problem by firmware update F21, but the recent updates for my dv5 have not done so. Please, I really like my laptop and I need this problem fixed. Your consideration would be greatly appreciated! Sincerely, *** I know some of you have already done this, but I think some solidarity on this might go further towards getting something done. Thanks!! ** Description changed: On resume from suspend in Ubuntu 8.10 (Intrepid Ibex) the ATA driver throws a series of exceptions, as a result the filesystems can not be accessed and the computer needs to be rebooted. Hibernate, however, does work and does not have this problem, suspend / resume only. The linux kernel version is the latest 2.6.27-7. * Update 16th of May 2009 * The problem remains unchanged under Ubuntu 9.04 (Jaunty Jackalope). The initial error message on resume is: btusb_intr_complete: hci0 urb f7d94a00 failed to resubmit (2) ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4 ata2: irq_stat 0x00000040, connection status changed ata1: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4 ata1: irq_stat 0x00000040, connection status changed sd 0:0:0:0: rejecting I/O to offline device PM: Device 0:0:0:0; failed to resume: error 65536 Then, as nothing is able function properly, the most repeated error message is as follows: ata1: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen ata1: SError: { DevExch } ata2: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen ata2: irq_stat 0x00000040, connection status changed ata2: SError: { DevExch } There are a variety of other error messages thrown about ext3 file systems not being to be re-mounted, but I haven't been able to capture those yet. I'm running a fresh copy of Ubuntu 8.10 (Intrepid Ibex), with the latest updates, on a reasonably new HP Pavilion dv5 (1075er) notebook. Rationale: Originally I posted my problem under bug #158050 but later I realised that this was for an older kernel version. Then I thought that bug #273323 would be a better fit, but that has since digressed into a KDE discussion, entirely irrelevant to my problem. I've looked at every Intrepid suspend / resume bug listed and none are specific to my distribution version, kernel version or hardware so I'm starting a new one. * Update 16th of May 2009 * There has been a Kernel Bug Report open on this for some time now http://bugzilla.kernel.org/show_bug.cgi?id=12276 + + * Update 18th of May 2009 * There is also evidence, anecdotal and + otherwise, to suggest that the same problem is present on HDX and some + other models of HP laptop. -- HP Pavilion dv5: ATA exception on resume from suspend https://bugs.launchpad.net/bugs/301353 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
