| Hi,
|
| I've run into a wierd problem with 2.6.0-test4-mm4 on an SMP Xeon
| 550Mhz system. I was dd'ing some images to floppy and when I used a
| bad floppy, it would read 17+0 blocks, write 16+0 blocks and then
| hang. At this point, I couldn't use the keyboard at all, and I got an
| error message about "lost serial connection to UPS", which is from
| apcupsd, which I have talking over my Cyclades Cyclom-8y ISA serial
| port card.
|
| At this point, the load jumps to 1, nothing happes on the floppy
| drive, and I can't input data to xterms. I can browse the web just
| fine using the mouse inside Galeon, and other stuff runs just fine. I
| can even cut'n'paste stuff from one xterm and have it run in another.
|
| But the only way I've found to fix this is to reboot, which requires
| an fsck of my disks, which takes a while. I'll see if I can re-create
| this in more detail tonight while at home, and hopefully from a
| console.
|
| Strangley enough, Magic SysReq still seems to work, since that's how I
| reboot. Logging out of Xwindows works, but then when I try to reboot
| the system from gdm, it hangs at a blank screen.
|
| Whee!

Yes, bad_flp_intr() has some problem(s). See
http://bugme.osdl.org/show_bug.cgi?id=1033 and
http://marc.theaimsgroup.com/?l=linux-kernel&m=105837886921297&w=2
It's on my long work list.
