The error occurred on an intel Pentium 3 (500 MHz) embedded system with 440BX chipset and 192 MB RAM. USB is handled by the 440BX (intel 82371 PIIX4). The UHCI driver shares interrupt 7 with an intel 82559ER 100 Mbit ethernet controller (which is driven by the e100 driver and active: As there is no local keyboard, I access the system by ssh). The system "disk" is a 128 MB CF card directly connected to the 440BX primary IDE port and running in PIO mode 2 at about 2 MB/sec peak (but it is idle most of the time). There is a SM712 VGA chip running in text mode, a 1000 HZ std PC timer, and no other "interesting" device (nothing else on the PCI bus or causing any interrupts). The error was reproduced with statically linked (no modules) vanilla-2.6.11, 2.6.11-gentoo-r3, and realtime-preempt-2.6.12-rc1-V0.7.41-11 kernels, all built with gcc 3.4.3. No SMP. USB-storage for the sticks. I tried with two different sticks (an old 64 MB USB 1.x and a 1 GB USB 2.x), both show the same problem on all USB interfaces on the target. The same dd command works fine on both sticks on my office PC. -- Klaus Kusche Entwicklung Software - Steuerung Software Development - Control KEBA AG A-4041 Linz Gewerbepark Urfahr Tel +43 / 732 / 7090-3120 Fax +43 / 732 / 7090-8919 E-Mail: [EMAIL PROTECTED] www.keba.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
