Hello!

I got two lockups with log messages. And messages about lost 
interrupts that did not cause a lockup. The kernel is 2.3.42.

Can someone explain what this lost interrupt, and waiting
for DMA is?

Lockup 1 was during unpacking of a kernel. hde: timeout waiting
for DMA was printed to the xterm when it froze.

Lockup 2 was a seti session. hde: timeot waiting for DMA was 
printed to the xterm.

The "This was no lockup" messages was with kernel 2.3.41 so this
may already be fixed.


Bo
