USB problems and 2.4.0 hangs
Hi all. I'd installed the backport of the USB patch (to 2.2.16) and had the following problem: After a few inches of printing a graphics page (ghostscript output), the whole printing job would just hang. Only exit was switching the printer on/off and removing the print job. The printer is an HP810C and (I suspect) the problem is at the VIA chipset (VT82C586). After a few frustrating tries, I moved to kernel 2.4.0-test7, suspecting that maybe there was a problem with the backport. Results: Exactly the same print problem: hangs after 5 - 10 cm of printing a graphics page (text mode works ok). But, after installing 2.4.0, yesterday, I had two misterious hangs of the operating system - apparently nothing to do with the tasks that were running - they were completely different. Just in case: the printer is driven by the apsfilter, which works fine when using the parallel port. Thanks on beforehand!

Re: USB problems and 2.4.0 hangs
Hi Randy. Sorry I didn't catch your reply, for some reason my mailclient didn't order it correctly. Anyway, I'm no kernel guru. I hope this is what you wanted: - I started with boot: Linux debug - The var/log/messages file did not register anything strange, just the correct registering of the printer - the var/log/syslog says: Oct 4 11:21:14 on6jc kernel: hub.c: already running port 2 disabled by hub (EMI Oct 4 11:21:25 on6jc kernel: hub.c: already running port 2 disabled by hub (EMI Oct 4 11:21:25 on6jc kernel: printer.c: failed reading usblp status I have the impression that the EMI message is wrong. I get this message each time I boot (In fact, the first line - at 11:21:14 - was the message at boot. The second line is when the print daemon awakens) - var/log/debug says: Oct 4 11:21:14 on6jc kernel: usb.c: kmalloc IF c3ff9420, numif 1 Oct 4 11:21:14 on6jc kernel: usb.c: new device strings: Mfr=0, Product=2, SerialNumber=1 Oct 4 11:21:14 on6jc kernel: usb.c: USB device number 1 default language ID 0x0 Oct 4 11:21:14 on6jc kernel: hub.c: ganged power switching Oct 4 11:21:14 on6jc kernel: hub.c: standalone hub Oct 4 11:21:14 on6jc kernel: hub.c: global over-current protection Oct 4 11:21:14 on6jc kernel: hub.c: power on to power good time: 2ms Oct 4 11:21:14 on6jc kernel: hub.c: hub controller current requirement: 0mA Oct 4 11:21:14 on6jc kernel: hub.c: port 1 is removable Oct 4 11:21:14 on6jc kernel: hub.c: port 2 is removable Oct 4 11:21:14 on6jc kernel: hub.c: local power source is good Oct 4 11:21:14 on6jc kernel: hub.c: no over-current condition exists Oct 4 11:21:14 on6jc kernel: hub.c: enabling power on all ports Oct 4 11:21:14 on6jc kernel: usb.c: hub driver claimed interface c3ff9420 Oct 4 11:21:14 on6jc kernel: hub.c: port 1 connection change Oct 4 11:21:14 on6jc kernel: hub.c: portstatus 100, change 3, 12 Mb/s Oct 4 11:21:14 on6jc kernel: hub.c: port 1 enable change, status 100 Oct 4 11:21:14 on6jc kernel: hub.c: port 2 connection change Oct 4 11:21:14 on6jc kernel: hub.c: portstatus 101, change 3, 12 Mb/s Oct 4 11:21:14 on6jc kernel: hub.c: portstatus 103, change 0, 12 Mb/s Oct 4 11:21:14 on6jc kernel: usb.c: kmalloc IF c3ee1980, numif 1 Oct 4 11:21:14 on6jc kernel: usb.c: new device strings: Mfr=1, Product=2, SerialNumber=3 Oct 4 11:21:14 on6jc kernel: usb.c: USB device number 2 default language ID 0x409 Oct 4 11:21:14 on6jc kernel: printer.c: usblp_control_msg: rq: 0x00 dir: 1 recip: 1 value: 0 len: 0x3ff result: 161 Oct 4 11:21:14 on6jc kernel: printer.c: usblp0 Device ID string [161]=MFG:HEWLETT-PACKARD;MDL:DESKJET 810C;CMD:MLC,PCL,PML;CLASS:PRINTER;DESCRIPTION:Hewlett-Packard DeskJet 810C;SERN:BR98R1S0B5FY;VSTATUS:$HB0$FC0,ff,DN,IDLE,CUT; Oct 4 11:21:14 on6jc kernel: printer.c: usblp_control_msg: rq: 0x01 dir: 1 recip: 1 value: 0 len: 0x1 result: 1 Oct 4 11:21:14 on6jc kernel: usb.c: usblp driver claimed interface c3ee1980 Oct 4 11:21:14 on6jc kernel: hub.c: port 2 enable change, status 101 Oct 4 11:21:14 on6jc kernel: hub.c: portstatus 103, change 0, 12 Mb/s Oct 4 11:21:14 on6jc kernel: hub.c: portstatus 103, change 0, 12 Mb/s Oct 4 11:21:14 on6jc kernel: usb.c: kmalloc IF c3ee1940, numif 1 Oct 4 11:21:14 on6jc kernel: usb.c: new device strings: Mfr=1, Product=2, SerialNumber=3 Oct 4 11:21:14 on6jc kernel: usb.c: USB device number 2 default language ID 0x409 Oct 4 11:21:14 on6jc kernel: printer.c: usblp_control_msg: rq: 0x00 dir: 1 recip: 1 value: 0 len: 0x3ff result: 161 Oct 4 11:21:14 on6jc kernel: printer.c: usblp0 Device ID string [161]=MFG:HEWLETT-PACKARD;MDL:DESKJET 810C;CMD:MLC,PCL,PML;CLASS:PRINTER;DESCRIPTION:Hewlett-Packard DeskJet 810C;SERN:BR98R1S0B5FY;VSTATUS:$HB0$FC0,ff,DN,IDLE,CUT; Oct 4 11:21:14 on6jc kernel: printer.c: usblp_control_msg: rq: 0x01 dir: 1 recip: 1 value: 0 len: 0x1 result: 1 Oct 4 11:21:14 on6jc kernel: usb.c: usblp driver claimed interface c3ee1940 Oct 4 11:21:14 on6jc kernel: VFS: Disk change detected on device sr(11,0) Oct 4 11:21:14 on6jc kernel: ISO 9660 Extensions: Microsoft Joliet Level 3 Oct 4 11:21:14 on6jc kernel: ISOFS: changing to secondary root Oct 4 11:21:14 on6jc kernel: VFS: Disk change detected on device sr(11,8) Oct 4 11:21:14 on6jc kernel: ISO 9660 Extensions: Microsoft Joliet Level 3 Oct 4 11:21:14 on6jc kernel: ISOFS: changing to secondary root Oct 4 11:21:14 on6jc kernel: VFS: Disk change detected on device fd(2,0) Oct 4 11:21:14 on6jc kernel: printer.c: usblp_control_msg: rq: 0x01 dir: 1 recip: 1 value: 0 len: 0x1 result: 1 Oct 4 11:21:25 on6jc kernel: hub.c: port 2 enable change, status 101 Oct 4 11:21:25 on6jc kernel: printer.c: usblp_control_msg: rq: 0x01 dir: 1 recip: 1 value: 0 len: 0x1 result: -84 Oct 4 11:21:25 on6jc kernel: hub.c: portstatus 101, change 0, 12 Mb/s Oct 4 11:21:26 on6jc kernel: hub.c: portstatus 103, change 0, 12 Mb/s Oct 4 11:21:26 on6jc kernel: usb.c: kmalloc IF c29aba80, numif 1 Oct 4 11:21:26 on6jc kernel: usb.c: new device str
Segfaults using xawtv
Hi... I _hate_ to do this, but I couldn't find (except for a reference to "others who have segfaults using glibc") no reference to this problem. Insmod of i2c, videodev and bttv succeed without problems or any message in /var/log/debug, messages or syslog. Also, though I'm surely no expert, I tested a bit with gdb & such, and suspect there may be a problem that's not directly xawtv/bttv related. Any suggestions?

(only name I found in your message) Thanks for the info! I just downloaded, compiled (no errors) and installed zapping, but no luck. The moment I enabled the composite input, the system crashes. It doesn't crash before, I guess, because by default the program is receiving TV, and no cables is connected - hence no image. This _does_ help to point to bttv (or the new i2c stack?) instead of xawtv as the culprit of the situation. Some time ago I tested a webcam from the university here and ran successfully an older version of bttv (with xawtv). I'll try to reinstall those next. But then I've also seen some rumors about differences in the kernels being the cause, and I'm not quite ready to go back to 2.2.10 or so. Anyway, thanks again, any suggestions welcome.

Conflict between ide and usb?
Hi all. I installed ueagle-atm, which, by itself, is working fine with an MT-810 modem. The problem I have, is that when I copy a file from a DVD to harddisk, the internet connection almost dies (it slows down terribly, so much so that established connections actually disconnect, ping looses packets, DNS lookup fails, etc). After copy ends, all returns to normal. The machine is an AMD64, still in x86 mode though. CPU activity is very low during the copy, so it's not a CPU problem. Kernel is 2.6.20.2. APIC is enabled. No error message found in either /var/log/messages or syslog. DVD and HD are on different IDE interfaces. Can anyone suggest where to start looking for a solution?

In this case SATA isn't used, as the copy is from IDE to IDE. But I doubt bandwidth has anything to do with it. The DVD transfer rate rarely reaches 3.3 MB/s - which by itself isn't normal. > You can confirm it by forcing the hard drive and/or DVD drive to a > lower speed if your BIOS allows it. No... I didn't find any way to lower the speed.

That was the problem! This is the first machine I bought assembled, and I hadn't noticed that the CD/DVD cables were the old 40 wire cables. I do hope this is the last of the problems. Thanks guys! Changed the cable, and speed went up from 3.3 to 19MB/s (probably limited by the older harddrive too)... Thas was spectacular! Of course, now DMA didn't switch off either.
