Hi list, Since the release of 3.7 my main computer has been panicking a couple of times on both 3.7.0 and 3.7.1 because of a 'dma_map_area overflow xx bytes'.
Example screen shot: http://www.tweek.dk/panic.jpg I can reproduce it somewhat easily by visiting http://www.openstreetmap.org/ and zoom erratically with the scroll-button on the mouse. The panic seems to occur on line 229 of arch/x86/kernel/amd_gart_64.c, and reverting commit aee77e4accbeb2c86b1d294cd84fec4a12dde3bd (r8169: use unlimited DMA burst for TX) seems to fix the problem for me (at least I've not been able to make it panic as before (yet)). lspci -v: 00:00.0 Host bridge: Advanced Micro Devices [AMD] nee ATI RS480 Host Bridge (rev 01) 00:02.0 PCI bridge: Advanced Micro Devices [AMD] nee ATI RS480 PCI-X Root Port 00:05.0 PCI bridge: Advanced Micro Devices [AMD] nee ATI RS480 PCI Bridge 00:12.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB600 Non-Raid-5 SATA 00:13.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI0) 00:13.1 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI1) 00:13.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI2) 00:13.3 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI3) 00:13.4 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI4) 00:13.5 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB Controller (EHCI) 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 13) 00:14.1 IDE interface: Advanced Micro Devices [AMD] nee ATI SB600 IDE 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 00:14.3 ISA bridge: Advanced Micro Devices [AMD] nee ATI SB600 PCI to LPC Bridge 00:14.4 PCI bridge: Advanced Micro Devices [AMD] nee ATI SBx00 PCI to PCI Bridge 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
