Aren't sed's addresses required to be cumulative across its input files? http://www.opengroup.org/onlinepubs/009695399/utilities/sed.html That makes sense for filter mode because it's equvalent to concatenating the files in advance: cat files ... | sed expression OTOH, in-place mode selected by a -i option can be seen as follows: for f in files ...; do sed expression $f $f.tmp mv $f $f.bak mv $f.tmp $f done I.e., each file preserves its individuality. This can be at logical conflict with cumulative addresses across all files. -- Yar ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
IRQ storm
Hello, I apologize for repeating post here, but on FreeBSD-questions mailing lists no one gave me an answer. I've changed motherboard recently (now it is Intel DP965LT) and now I have my PC slowed down considerably. vmstat -i shows a huge amount of interrupts on irq17: atapci0: interrupt total rate irq1: atkbd0 12535 4 irq12: psm0 9410 3 irq17: atapci0 189627864 61507 irq19: atapci1+ 391391126 irq20: em0 29076 9 irq22: pcm020557 6 cpu0: timer 6133486 1989 cpu1: timer 6133460 1989 Total 202357779 65636 Since this problem came, my Xorg stopped seeing my PCIE video card. I guess these two could be related. I've tried to boot in safe mode and with ACPI disabled but the problem persists. I've rebuild the kernel with minimal set of options and devices, but it did not help. I've disabled all non-vital devices from BIOS, tried to put my SATA drive in Native and legacy modes, tried with S.M.A.R.T. disabled, disabled USB, FireWire, NIC, serial and parallel ports, floppy controller, but nothing helped. What else should I try? I've attached my dmesg output (with boot_verbose=YES in loader.conf, that's why it is so large) I do not have atapicam enabled. Here is my kldstat output: # kldstat Id Refs AddressSize Name 1 14 0xc040 3703a4 kernel 21 0xc0771000 6ea8 linprocfs.ko 32 0xc0778000 1adb8linux.ko 41 0xc0793000 2364 accf_http.ko 51 0xc0796000 aa74 cpufreq.ko 61 0xc07a1000 59a50acpi.ko 71 0xc4a7a000 3000 pflog.ko 81 0xc4a7d000 2d000pf.ko I've checked my kernel configuration file and I do not have it there either. What else should I check? After several days of playing in console looking for hardware-related tools, I found that after running this: # atacontrol reinit ata2 the storm was gone. My only HDD in on ata4: # atacontrol info ata4 Master: ad8 ST3160812AS/3.AAD Serial ATA II Slave: no device present After this my Xorg is OK again. Now my problem is worked around putting this command (atacontrol reinit ata2) into /etc/rc.local, but what is the cause? Is it a bug? Is there a problem with my hardware?

Re: Have people started working on any Google Summer of code 2007 project?
Hi, Is FreeBSD restricting non-students from not taking up any project that is 'suitable for summer of code'? For eg. I was planning to take up the 'super tunnel daemon' project some time back. I had done some initial work but now i find that it has also been marked as 'Suitable for summer of code'. I am no longer a student. I am working currently at a firm. So i dont think that i will be eligible for the summer of code. Can i still take up the project or am i forced to take up those that are not marked as 'suitable for summer of code'? Also, if someone has taken a summer of code project can no-one else take it up as a normal project to contribute to FreeBSD ? Awaiting a reply, Ajay. On 3/26/07, Julian H.

(Though I have no special status other than being last poster), to ensure you get some reply, My 2c. : No can stop anyone working; Be a shame though if 2 people work one's effort was not used. I suppose as SoC deadline was yesterday it'll take a while for google to publish their sponsoring list. If 2 people develope same thing: whose code will be commited will I suppose be decided on which arrives first /or seems best code, hopefully independent of status of author eg student V. independent.
