| |
Hi! I've posted something about this to comp.os.linux.development.system but got no response - I'm wondering if anyone here might know more about it.
The problem is that writing floppies with dd causes both of my machines to lock up solid when running any kernel >= 2.1.94, while kernels <= 2.1.91 and 2.0.33 don't do this. (2.1.92 is just generally unstable, while 2.1.93 doesn't boot, so I haven't tried it on them). The floppy driver is loaded as a module on all these kernels.
Both boxes are uniprocessor SCSI-based machines, using the ncr53c8xx driver. I've heard a bit about floppy-related hangs on SMP machines, but nothing about uniprocessors. The dd version is GNU fileutils 3.16. Unfortunately, when it locks up, it doesn't leave any useful information in the logs - it just hangs, without responding to the SysRq key or anything.
I'm not a kernel hacker so I'm not sure how to go about diagnosing the problem. Regardless, it's not life-threatening - I just thought I'd let y'all know it exists.
