From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Description of problem: Problem: When usb-core is compiled as a module, system locks sporadically - no console access, cannot ssh, etc. If left alone, it will come back after some time (up to an hour). (See attached /var/log/messages.) If I compile a custom kernel, and make usb support part of the kernel, instead of a module, I never experience this issue. OS is installed on 1 SCSI disk Using RAID0 array with 8 disks for file server partition I think raid0 is significant. Version-Release number of selected component (if applicable): kernel-smp-2.4.20-19.9 How reproducible: Always Steps to Reproduce: 1. Boot stock kernel 2. Perform some I/O instensive operation (extract kernel source) 3. When machine locks, do not reboot it. Leave it alone. Additional info:
Created attachment 93790 [details] System info
Created attachment 93791 [details] /var/log/messages This /var/log/messages excerpt shows the system was locked from 15:57 until 16:39 Lots of SCSI debug info
What does happen if you press NumLock, does the LED switch on/off?

Sorry for never following up on this defect... When I stated above "If I compile a custom kernel, and make usb support part of the kernel, instead of a module, I never experience this issue," I was wrong. The issue still happened (just took a few days). I ended up putting the SCSI card and disk array in a different PC (also an HP Kayak, but a newer model). The problem went away after that. So, I can no longer reproduce the issue, or do any more tests. The problem was either a hardware compatibility issue, or perhaps a bad motherboard, CPU, RAM, or other hardware. This bug can be closed.
