Due to workarounds for a bug, * this time source is slow. If you are sure your timer does not have * this bug, please use "pmtmr_good" to disable the workaround It looks like my chipset is in the kernel's "gray-list" for having a hardware timer bug. So seeing as I *do* have the relevant hardware, what would I need do to determine whether this chipset actually does have the bug or not, please? 00:00.0 Host bridge: Intel Corporation E7505 Memory Controller Hub (rev 03) 00:01.0 PCI bridge: Intel Corporation E7505/E7205 PCI-to-AGP Bridge (rev 03) 00:02.0 PCI bridge: Intel Corporation E7505 Hub Interface B PCI-to-PCI Bridge (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 81) 00:1f.0 ISA bridge: Intel Corporation 82801DB/DBL (ICH4/ICH4-L) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 01) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) Thanks, Chris ___________________________________________________________ The all-new Yahoo!
