2008-10-06x86 ACPI: Blacklist two HP machines with buggy BIOSesRafael J. Wysocki1-0/+16
There is a bug in the BIOSes of some HP boxes with AMD Turions which connects IO-APIC pins with ACPI thermal trip points in such a way that if the state of the IO-APIC is not as expected by the (buggy) BIOS, the thermal trip points are set to insanely low values (usually all of them become 16 degrees Celsius). As a result, thermal throttling kicks in and knock the system down to its shoes. Unfortunately some of the recent IO-APIC changes made the bug show up. To prevent this from happening, blacklist machines that are known to be affected (nx6115 and 6715b in this particular case). This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11516 listed as a regression from 2.6.26. On my box it was caused by: commit 691874fa96d6349a8b60f8ea9c2bae52ece79941 Author: Maciej W.

Rozycki <[email protected]> Signed-off-by: Ingo Molnar <[email protected]> and the whole story is described in this (huge) thread: http://marc.info/?l=linux-kernel&m=121358440508410&w=4 Matthew Garrett told us about that happening on the nx6125: http://marc.info/?l=linux-kernel&m=121396307411930&w=4 and then Maciej analysed the breakage on the basis of a DSDT from the nx6325: http://marc.info/?l=linux-kernel&m=121401068718826&w=4 As far as the Dmitry's and Jason's boxes are concerned, I recognized the symptoms and asked them to verify that the blacklisting helped. It appears that the buggy BIOS code has been copy-pasted to the entire range of machines, for no good reason. Signed-off-by: Rafael J.

The Swarm IDE driver uses a release method which is defined in the driver itself thus potentially oopsable.

Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes, judging from the code immediately preceding this check. So, we must never try to "split" the PRD for TRM290. This is probably never hit anyway -- with the DMA buffers aligned to at least 512 bytes and ATAPI DMA not being used for non block I/O commands...

Likewise, with ioctl VIDIOC_S_FMT, we are supposed to fill the bytes-per-line value. And we shouldn't fail if the caller sets the initial value to something different from 0.

If a bttv device without radio and one with radio are installed on the same system, and the one without radio is registered first, then radio_open checks for the radio device number of a bttv device that has no radio function, and this breaks.
