Also, how reproducible is the problem? I don't think there's any difference which can trigger or prevent the problem between the kernels you used. Can you please try to determine how deterministic the problem is? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(As expected it also doesn't matter if the proprietary NVidia module is present or not, but one never knows with non-OSS modules, so I tried that as well.) The hardware should be OK, or else going back to .27.4 in comment #2 wouldn't have fixed the problem. As this appears even with the 11.1 kernel and the ASUS P5B series (all with the same SATA/PATA chips AFAIK) isn't that uncommon, I wonder that this isn't reported more often, but people seeing it might not notice it unless they actually need access to their PATA drives and wouldn't connect a constant churn on the main harddisk to this failure unless they know to look into /var/log/messages. Given the mailing list message I linked into comment #0, which has the same failure on an early 2.6.28, I suspect someone might have brought this infection to the openSUSE .27 kernel with backporting some new stuff to make the 11.1 release. Unfortunately, I can't verify that, as the Kernel:Vanilla OBS repo doesn't have any near-to-recent kernel, only a .27-rc3 version. The constant writing of this error to /var/log/messages a few times a second makes the whole system slow to a crawl, I could only stop this by turning off syslog for now, as unfortunately I also don't have the .27.4 kernel around any more that worked without problems until I upgraded Factory again yesterday. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

That part of code (SFF HSM) has been quite stable lately and I don't have any related bug report on openSUSE or upstream either, so I'm a bit lost. I'll look at the diff between 2.6.27.4 and 7 and see whether I can find something.

If you're not familiar with kernel building, I can build rpms for you but it usually goes faster for both sides if you can test patches.

I'd rather have rpms I can test, as this is my production machine (yes, I'm running Factory in a production environment) and I don't want it to be "down" (i.e. rebooting etc.) for too long. If there are rpms of vanilla 2.6.27.x I can install, it might be a good idea to try, as I somehow still suspect it's something openSUSE backported from the .28 cycle, esp. as the thread I referred to in comment #0 (which you apparently have looked at as well) looks quite similar from the error messages, and it's also a CD-RW/DVD-ROM combo drive there, just like in my case, only it's on SATA there and I have it on PATA, but with both handled by libata nowadays I guess that could still lead to the same code. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Can I use the 64bit kernel on a otherwise 32bit system (as in software, the hardware is 64bit-capable)? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'm not sure why the problem didn't trigger before but the difference could be caused by preferring hardreset over softreset, but behaviors like this can also depend on strange things like media is presence in the drive or what type of media. Can you please post the output of "hdparm -I /dev/sr0" so that the drive can be quirked? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
