Linice

If you're in the market for a source-level kernel debugger for your x86 system, Linice may be just what you're looking for. This program has been designed with SoftIce for MS Windows users in mind, with a similar look and feel to that popular program. However, even if you're not already familiar with SoftIce, Linice is easy to get the hang of quickly.

One of the top features of Linice is its ability to break into a running kernel at any time with a simple hotkey. This program is also capable of supporting breakpoints and single-step modes on user programs, the kernel, or even individual modules.

Linice has also been designed with versatility in mind, offering support for a wide range of adapters including the VGA frame buffer, X Window System, serial connections, and even monochrome adapters.

If you're wondering what's new in this release, there are a few notable fixes worth highlighting. First, there was previously a bug in Linsym where getlogin() would return NULL for some kernels. This has been fixed in this latest release of Linice. Additionally, this update has resolved a linsym segfault that had been reported by multiple users.

Overall, if you're looking for a powerful and user-friendly kernel debugger option, Linice is worth your consideration.
