From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: After plugging in the USB memory stick, it doesn't work at all. I also cannot read the contents of /proc/bus/usb/devices for some time (few seconds), and later it doesn't show the memory stick. Some error messages, which are reproduced below, are displayed or stored in a log file. Kernel modules loaded include usb-storage and sd_mod. Attempt to remove sd_mod results in a segmentation fault. Version-Release number of selected component (if applicable): kernel-2.4.20-9 How reproducible: Always Steps to Reproduce: 1. Turn on the machine, wait for it to boot. 2. Plug in memory stick. 3. Watch the results. Actual Results: Error messages, problems with /proc/bus/usb/... Expected Results: Memory stick ready to be mounted as /dev/sda1. Additional info: Some of error messages: Apr 21 23:44:58 dhcp03 kernel: usb-uhci.c: interrupt, status 2, frame# 117 Apr 21 23:44:59 dhcp03 kernel: usb_control/bulk_msg: timeout [...] Apr 21 23:45:25 dhcp03 kernel: scsi: device set offline - not ready or command [...] Apr 21 23:46:08 dhcp03 kernel: resize_dma_pool: unknown device type -1 Machine I use is an old, 440LX chipset-based Pentium II, which uses usb-uhci driver. Memory stick works OK with Redhat 7.3, and with Redhat 9 using a 2.4.18-3 kernel (from RH 7.3).
Please try the 2.4.20-18 errata. Apparently, upstread destroyed usb-uhci. If that fails, we'd need a step-by-step resolution, but I hope not.
After installing 2.4.20-18 everything seems to be fine.
