works, it should just keep writing 0's to the iomemory forever (at least as I understand it). When I run insmod on this device driver I see the following output: start=20000000 size=04000000 memset c0580000 memset c0580000 memset c0580000 ... ... ... And this goes on for quite some time. Eventually it will stop, moments later I will see a kernel panic with the following output: > pci 1320 bus fatal error memset c0580000 > memset c0580000 > memset c0580000 > Data bus error, epc == c027a64c, ra == 800aa27c > Oops[#1]: > Cpu 0 > $ 0 : 00000000 10008400 c0363050 00063050 > $ 4 : 00000037 82937800 8109d000 10008401 > $ 8 : 10008400 1000001f 80320000 80320000 > $12 : 80320000 00000001 83133bf8 8031c960 > $16 : 8311c600 00000080 00000001 00000037 > $20 : c02815e8 802e1ae4 c025a000 8008cde4 > $24 : 00000008 00000000 > $28 : 83132000 83133be8 c02815ac 800aa27c > Hi : 00000000 > Lo : 00000800 > epc : c027a64c Tainted: P > ra : 800aa27c Status: 10008403 KERNEL EXL IE > Cause : 1080801c > PrId : 00061200 > Modules linked in: tmman1700(P) mousedev usbhid usb_storage phStbFB(P) > phStbFBRead(P) phStbVideoRenderer(P) phStbVideoRenderer_Layer(P) > phStbStreamingSystem(P) phStbDraw(P) snd_usb_audio snd_usb_lib snd_rawmie > Process insmod (pid: 790, threadinfo=83132000, task=833e1278) > Stack : 801ecd20 801ecd20 00000000 00000037 8311c600 00000080 00000001 > 800aa27c > 00000000 8008c23c 0000004f 810b9c00 802f7dc0 810c3c00 00000037 > 810b9c00 > 800aa398 800aa340 10008400 8008c31c 80320000 80320000 00000000 > 04000000 > c0280000 8006386c 80320000 c027e814 10008401 8031c570 80061310 > 802e1ae4 > c025a000 8008cde4 00000008 00000000 00000000 80062040 83132000 > 83133ca8 > ... > Call > Trace:[<801ecd20>][<801ecd20>][<800aa27c>][<8008c23c>][<800aa398>][<800aa340>][<8008c31c>][<8006386c>][<80061310>][<8008cde4>][<80062040>][<80086918>][<8019f924>][<8008cde4>][

A bus https://www.linux-mips.org/archives/linux-mips/2008-02/msg00030.html is a communication unit that allows the CPU to interact with peripherals, there are different type of buses such as PCI, I2C, MDIO, Memory Buses, etc. Normally each bus would have its own protocol for transmitting data across devices, for example in the case of PCI you can have timeout errors or windows errors (data is directed to unknown addresses/devices). In memory, bus errors would refer to https://www.careercup.com/question?id=13871739 alignment but other errors could be attributed to physical HW problems such as faulty connections. Other type of bus errors could be single and multiple bit errors, this could be addressed by using ECC memory. - gmoque July 27, 2012 | Flag Reply Comment hidden because of low score.

For example AHB-lite (Advanced High performance Bus) feature for arm. - abhi.jais.86 December 15, 2012 | Flag Comment hidden because of low score.

Let me know if it is right or not. - Akshay Kulkarni January 12, 2013 | Flag Comment hidden because of low score.

Now I was trying to install Nvidia drivers according to the tutorial. At this point I noticed the problem with my system. When I switched to command line mode ( Ctrl+Alt+F1) there was continuous error display on my console. So I accessed my syslog to verify it. The same error was flushing my /var/log/syslog file. Below is the error I got: Mar 20 05:27:41 Asus-X556UF kernel: [ 615.993338] pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000 Mar 20 05:27:41 Asus-X556UF kernel: [ 615.993342] pcieport 0000:00:1c.5: [ 0] Receiver Error (First) Mar 20 05:27:41 Asus-X556UF kernel: [ 615.993351] pcieport 0000:00:1c.5: AER: Multiple Corrected error received: id=00e5 Mar 20 05:27:41 Asus-X556UF kernel: [ 615.993700] pcieport 0000:00:1c.5: can't find device of ID00e5 Mar 20 05:27:41 Asus-X556UF kernel: [ 615.993723] pcieport 0000:00:1c.5: AER: Multiple Corrected error received: id=00e5 Mar 20 05:27:41 Asus-X556UF kernel: [ 615.994075] pcieport 0000:00:1c.5: PCIe Bus Error: severity=Correct
