Receiving bytes over a serial line with low latency mode causes a deadlock (at least on 2.6.7+2.6.10 on x86), which stop the computer from responding. R/W access to /dev/ttySx and a device, which sends bytes to the computer, are sufficient to exploit it.
There were some messages about it on lkml. The kernel sources 2.6.10-5 seem to contain no fix for it. In Bitkeeper Repository, it is fixed by the following small patch: http://linux.bkbits.net:8080/linux-2.6/cset%4042084ee5WBMJKW89M3BdT38Ykkl5eA?nav=index.html|[EMAIL PROTECTED] I think, it should be easy backportable to older versions. mfg Martin K�gler PS: Please CC me on replies. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
