HP Probook 4510s Oops

HP ProBook 4510s BIOS 68PZI Ver. F.17 oops on Fedora release 13 (Goddard) kernel-2.6.34.6-47.fc13.x86_64

Recently I started the Windows 7 Home Premium 32-bit operating system on my HP ProBook 4510s laptop. This would not be any news for an average user, but for me it was. The Windows 7 Home Premium 32-bit operating system is a kind of a tamagotchi on my laptop, as I paid for a Windows Vista Home Premium32-bit operation system, HP promised a free upgrade to the Windows 7 Home Premium 32-bit operating system. They had chosen a company called Arvato Digital Services for that handling upgrade, which did a fascinating job making the life many HP hardware users, which were running the Windows Vista operating system, softly speaking, very interesting. You can google for 'HP Windows 7 Upgrade Arvato Disgusted' and you'll see in the HP Support forums what I mean. This is one of the aspects in which the Windows 7 Home Premium 32-bit operating system is a tamagotchi on my laptop. The second aspect is that I switch from time to time from Fedora 13 to Windows 7 Home Premium 32-bit operating system in order to get the latest Windows updates, taking advantage of the Windows Genuine Advantage program. After that I switch to Fedora 13, on which I work most of the time. I would like to kindly mention that according to my experience of using Fedora 13 and my experience of using Windows 7 Home Premium 32-bit operating system, Fedora 13 is a much better operating system.

So I started the Windows 7 Home Premium 32-bit operating system on my HP ProBook 4510s laptop. The HP Support Assistant started an automatic check-up. It showed that the BIOS  firmware must be updated. I selected the update and started it. The automatic upgrade failed as I  had set a password for access to the BIOS settings. I suspected the BIOS password and I was right. When I downloaded the update from the HP Support downloads. I started it. It asked for the BIOS password, then the update from 68PZI Ver 68PZI Ver. F.12 to 68PZI Ver. F.17 flashed itself into the BIOS memory. I restarted the laptop. Then I restarted in in Fedora 13. I started looking intothe output of dmesg as if I suspected something. Yes, there was an oops. While I was looking at it, the ABRT showed a notification about a crash in the kernel package. I submitted the bug report. However I think the problem is in the HP BIOS, not in the Fedora kernel.

Today there was an update of the kernel package to  kernel-2.6.34.6-47.fc13.x86_64. The oops is still there, maybe I must disable the check for the Intel IOMMU. I didn't look into the Windows 7 Home Premium 32-bit operating system logs, but I think Microsoft again hid something from the eyes of the end users.

Who on the earth wrote an operating system, the right of using of which I bought, just to stay as a tamagotchi on my laptop? Who has such good marketing, who fooled me to to buy their product instead of making a donation to the company which develops the operating system I use? According to the rules of Microsoft for using of their trademarks, I should mention that Windows is a trademark of Microsoft Corporation. Here I go. I am going to mention it below.

Windows is a trademark of Microsoft Corporation.

I should have bought Fedora. After all, I use it for business.

Enough talking. You wonder where is the oops? Here it is:
