Are others experiencing problems as well? I am considering reverting the Debian packages to 2.4.24-1um, which was the last version which was stable for me (it had only one frustrating hostfs bug, where readdir() would read forever). ----- Forwarded message from Marius Gedminas ----- Date: Tue, 29 Jun 2004 16:46:21 +0100 From: Marius Gedminas Resent-From: Marius Gedminas To: Debian Bug Tracking System Subject: Bug#256873: user-mode-linux: fails to start (kernel panic) Package: user-mode-linux Version: 2.4.26-1um-1 Severity: important After 2.4.26-1um-1 fell into testing (replacing 2.4.24-1um-2), my UML instances fail to start with a kernel panic.
