I don't understand why you recompile the kernel for something that is a module option..... Can you reproduce the same hang by using the correct method for multi-lun setups?
- When using RAID storage configured with Logical Unit Numbers (LUNs)
greater than zero, it is necessary to enable LUN support by adding
the following entry to the /etc/modules.conf file:
options scsi_mod max_scsi_luns=255
After modifying modules.conf, it is necessary to rebuild the initial
ramdisk using `mkinitrd`. Refer to The Official Red Hat Linux
Customization Guide for more information about creating the ramdisk
image with mkinitrd.
It disappear after I use up2date to change kernel. I think I made a mistake that build old kernel with RAM disk as a module, as it is needed in initrd. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ia64; en-US; rv:1.4) Gecko/20030709 Description of problem: This bug found on both IA64 and i386 platform. I install the usb-storage for a 6-in-1 card reader, if CONFIG_SCSI_MULTI_LUN not selected, then only one SCSI device can run but it work. If CONFIG_SCSI_MULTI_LUN selected, then the system hang up after the driver loaded, the driver initialization seems completed. I already try the official linux kernel 2.4.21 without this problem. Already tried RedHat kernel 2.4.21-1.1931.2.349.2.2.ent and 2.4.21-1931.2.389.ent, both failed. Version-Release number of selected component (if applicable): usb-storage,scsi How reproducible: Always Steps to Reproduce: 1.Use 'make menuconfig' to turn on CONFIG_SCSI_MULTI_LUN 2.Select USB storage driver as module. 3.Build new driver and new kernel 4.Use new driver and kernel. 5.After loading driver, system will hang, if not, it will after mounting a file system of the card Actual Results: System hang, need power down or reset Expected Results: card should be mounted as usual Additional info: Use PQI 7-in-1 card reader, this is a standard usb storage type device and can work with out-of-box usb-storage driver.
